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>
using namespace std;
bool isPrime(int n) {
  if (n <= 3) {
    return n > 1;
  } else if (n % 2 == 0 || n % 3 == 0) {
    return false;
  } else {
    for (int i = 5; i * i <= n; i += 6) {
      if (n % i == 0 || n % (i + 2) == 0) {
        return false;
      }
    }
    return true;
  }
}
int main() {
  int n;
  cin >> n;
  for (int k = 2; k <= n / 2; k++) {
    if (!isPrime(k) && !isPrime(n - k)) {
      cout << k << " " << n - k << "\n";
      return 0;
    }
  }
}
