A. Design Tutorial: Learn from Mathtime limit per test1 secondmemory limit per test256 megabytesinputstandard inputoutputstandard outputOne 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.InputThe only line contains an integer n (12 ≤ n ≤ 106).OutputOutput 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.ExamplesInput12Output4 8Input15Output6 9Input23Output8 15Input1000000Output500000 500000NoteIn 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.
