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 CPP):

Solution:
#include <bits/stdc++.h>
int f(int n) {
  long long int i;
  for (i = 2; i <= n / 2; i++) {
    if (n % i == 0) return 0;
  }
  return 1;
}
int main() {
  long long int a, b, c, i, k, j, n;
  scanf("%lld", &n);
  if (n % 2 == 0) {
    a = f(n / 2);
    if (a == 0) printf("%lld %lld\n", n / 2, n / 2);
    if (a == 1) {
      b = n / 2;
      c = n / 2;
      for (i = 1;; i++) {
        b++;
        c--;
        j = f(b);
        k = f(c);
        if (j == 0 && k == 0) {
          printf("%lld %lld\n", b, c);
          break;
        }
      }
    }
  }
  if (n % 2 != 0) {
    a = f(n - 4);
    if (a == 0) printf("%lld 4\n", n - 4);
    if (a == 1) {
      b = 4;
      c = n - 4;
      for (i = 1;; i++) {
        b += 2;
        c -= 2;
        j = f(b);
        k = f(c);
        if (j == 0 && k == 0) {
          printf("%lld %lld\n", b, c);
          break;
        }
      }
    }
  }
