B'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. The only line contains an integer n (12 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89106). Output two composite integers x and y (1 xe2 x80 x89< xe2 x80 x89x, xe2 x80 x89y xe2 x80 x89< xe2 x80 x89n) such that x xe2 x80 x89+ xe2 x80 x89y xe2 x80 x89= xe2 x80 x89n. If there are multiple solutions, you can output any of them. 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.'...
