Problem: One way to create a task is to learn from math. You can generate some random math statement or modify some theorems to get something new and build a new task from that.

For example, there is a statement called the "Goldbach's conjecture". It says: "each even number no less than four can be expressed as the sum of two primes". Let's modify it. How about a statement like that: "each integer no less than 12 can be expressed as the sum of two composite numbers." Not like the Goldbach's conjecture, I can prove this theorem.

You are given an integer n no less than 12, express it as a sum of two composite numbers.

Input

The only line contains an integer n (12 ≤ n ≤ 106).

Output

Output two composite integers x and y (1 < x, y < n) such that x + y = n. If there are multiple solutions, you can output any of them.

Examples

Input

12


Output

4 8


Input

15


Output

6 9


Input

23


Output

8 15


Input

1000000


Output

500000 500000

Note

In the first example, 12 = 4 + 8 and both 4, 8 are composite numbers. You can output "6 6" or "8 4" as well.

In the second example, 15 = 6 + 9. Note that you can't output "1 14" because 1 is not a composite number.

Solution (in JAVA):

Solution:
import java.util.Scanner;
public class learnFromMath{
       public static void main(String[] args)
       {
              Scanner sc=new Scanner(System.in);
              int n=sc.nextInt();
              int a,b;
              if(n%2==0)
              {
                    if(composite(n/2))
                    {
                    	System.out.println(n/2+" "+n/2);
                    }
                    else
                    {
                    	System.out.println((n/2-1)+" "+(n/2+1));
                    }
              }
              else
              {     
                   if(composite(n/2)&&composite(n/2+1))
                   {
                	   System.out.println(n/2+" "+(n/2+1));
                   }
                   else if(composite(n/2-1)&&composite(n/2+2))
                   {
                	   System.out.println((n/2-1)+" "+(n/2+2));
                   }
                   else
                   {
                	   System.out.println((n/2-2)+" "+(n/2+3));
                   }
                   
              }
       }
       
       static boolean composite(int x){
    	   boolean flag=false;
    	   for(int i=2;i<x/2;i++)
    	   {
    		   if(x%i==0)
    		   {
    			   flag=true;
    		   }
    	   }
    	   
    	   return flag;
    	   
       }
}
