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;
unsigned long long total;
vector<vector<int> > vec(50000 + 9);
;
int n;
void topsort(int index, vector<int> toparr) {
  toparr[index]--;
  for (int i = 0; i < vec[index].size(); i++) toparr[vec[index][i]]--;
  bool good = 1;
  for (int i = 0; i < n && good; i++)
    if (toparr[i] != -1) good = 0;
  if (good) {
    total++;
    total %= 1000000007;
  }
  for (int i = 0; i < n; i++)
    if (toparr[i] == 0) topsort(i, toparr);
}
int main(int argc, char** argv) {
  int n;
  cin >> n;
  if (n % 2 == 0)
    cout << n - 4 << " " << n - (n - 4) << endl;
  else
    cout << n - 9 << " " << n - (n - 9) << endl;
  return 0;
}
