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 PYTHON3):

Solution:
import math

def is_composite(num):
    if num <= 2:
        return False
    if num % 2 == 0:
        return True
    max = math.ceil(math.sqrt(num))
    for n in range(3, max+1, 2):
        if num % n == 0:
            return True
    return False


def main():
    n = int(input())
    a = n//2
    b = math.ceil(n/2)
    while True:
        if is_composite(a) and is_composite(b):
            print(str(a) + ' ' + str(b))
            break
        else:
            a-=1
            b+=1


main()
