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.
输入描述:
The only line contains an integer n(12 ≤ n ≤ 106).


输出描述:
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.
示例1

输入

12<br />15<br />23<br />1000000<br />

输出

4 8<br />6 9<br />8 15<br />500000 500000<br />

备注:
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.
