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_472A {
    public static void main(String[] args) {
        int n = new Scanner(System.in).nextInt();
        int a = n / 2, b = n - a;
        while (a > 3 && b < n) {
            if (!prime(a) && !prime(b))
                break;
            a--;
            b++;
        }
        System.out.println(a + " " + b);
    }

    public static boolean prime(int num) {
        int lim = (int)Math.sqrt(num);
        for (int i = 2; i <= lim; i++)
            if (num % i == 0)
                return false;
        return true;
    }

}
