The great mathematician DreamGrid proposes a conjecture, which states that:

Every positive integer can be expressed as the sum of a prime number and a composite number.
DreamGrid can’t justify his conjecture, so you are invited to write a program to verify it. Given a positive integer n, find a prime number x and a composite number y such that x+y=n.
A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. Note that 1 is neither a prime number nor a composite number.

Input
The input contains multiple cases. The first line of the input contains a single integer T (1≤T≤105), the number of cases.

For each case, the only line of the input cont
