Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627514, here are decompositions:

3 + 31627511 = 31627514
13 + 31627501 = 31627514
31 + 31627483 = 31627514
103 + 31627411 = 31627514
157 + 31627357 = 31627514
181 + 31627333 = 31627514
211 + 31627303 = 31627514
271 + 31627243 = 31627514

Showing the first eight; more decompositions exist.
