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 PYTHON):

Solution:
def get_is_prime(n):
    # find all primes, up to ncrt
    is_prime = [False, False]
    is_prime.extend([True for _ in xrange(2, n + 1)])

    for i in xrange(2, n + 1):
        if not is_prime[i]:
            continue
        for j in xrange(i + i, n + 1, i):
            is_prime[j] = False
        
    return is_prime

def ni():
    return int(raw_input())

n = ni()

a = n / 2
b = n - a
if a > b:
    a,b = b,a

is_prime = get_is_prime(n)

while is_prime[a] or is_prime[b]:
    a -= 1
    b += 1

print a, b
