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:
# http://codeforces.com/problemset/problem/472/A

def isPrime(number):
	if number % 2 == 0:
		return False
	for x in range(3, int(number**0.5) + 1, 2):
		if number % x == 0:
			return False
	return True

inputNumber = int(input())
firstVal = 3
notDone = True
# if the first val isn't prime, and the second val isn't then they're composite.
while notDone and firstVal < (inputNumber / 2):
	firstVal += 1
	if not isPrime(firstVal):
		secondVal = inputNumber - firstVal
		if not isPrime(secondVal):
			notDone = False
print "%d %d" % (firstVal, secondVal)
