roblem Description
According to Goldbach’s conjecture, every even number can be expressed as a sum of two odd primes. Which numbers can be expressed as the sum of two cubes?
Input
For each test case, a line will contain a positive integer n which will be at most one million.
The last line will contain the integer 0, which should not be processed.
Output
For each test case, output two integers x and y such that x3 + y3 = n. If there are many such pairs of numbers, choose x to be as small as possible. If there are no such pairs, output “Impossible”.
