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 Test {

   
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        int[] arr = {2, 3, 4, 5, 6, 7, 8, 9, 10};
        int n = input.nextInt();
        int x = 0;
        int y = 0;

        int n1 = n / 2;
        x = n - n1;

        y = n - x;
       
          if(n%2==0)
            {
                x=8;
                y=n-8;
                System.out.println(x+ " " + y);
            }
            else if(n%2!=0)
            {
                x=9;
                y=n-9;
                System.out.println(x+" "+y);
                
            }
  
            
//               else
//            {
//               x+=2;
//               y-=2;
//               System.out.println(x+" "+y);
//               
//            }
           
        
            
    }
