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>
bool fun(long long a);
using namespace std;
int main() {
  long long num, num1, num2;
  cin >> num;
  if (num % 2 == 0) {
    num1 = num / 2;
    num2 = num / 2;
    while (!fun(num1) || !fun(num2)) {
      num1 -= 1;
      num2 += 1;
    }
  } else {
    num1 = num / 2;
    num2 = num / 2 + 1;
    while (!fun(num1) || !fun(num2)) {
      num1 -= 1;
      num2 += 1;
    }
  }
  cout << num1 << " " << num2;
}
bool fun(long long a) {
  int c = 0;
  for (int i = 2; i < a; i++) {
    if (a % i == 0) {
      c = 1;
      break;
    }
  }
  return c == 1;
}
