Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31632, here are decompositions:

5 + 31627 = 31632
31 + 31601 = 31632
59 + 31573 = 31632
89 + 31543 = 31632
101 + 31531 = 31632
151 + 31481 = 31632
163 + 31469 = 31632
239 + 31393 = 31632

Showing the first eight; more decompositions exist.
