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;
int main() {
  ios_base::sync_with_stdio(0);
  cin.tie(0);
  cout.tie(0);
  int prime[1000001];
  for (long long int i = 1; i <= 1000000; i++) prime[i] = 1;
  prime[0] = 0;
  prime[1] = 0;
  for (long long int i = 2; i <= 1000; i++)
    if (prime[i] == 1)
      for (long long int j = 2; i * j <= 1000000; j++) prime[i * j] = 0;
  long long int n;
  cin >> n;
  long long int a = 2;
  while (prime[a] + prime[n - a] > 0) a++;
  cout << a << " " << n - a << "\n";
  cerr << "Time : " << (double)clock() / (double)CLOCKS_PER_SEC << "s\n";
  return 0;
}
