Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627542, here are decompositions:

5 + 31627537 = 31627542
31 + 31627511 = 31627542
41 + 31627501 = 31627542
59 + 31627483 = 31627542
131 + 31627411 = 31627542
151 + 31627391 = 31627542
223 + 31627319 = 31627542
239 + 31627303 = 31627542

Showing the first eight; more decompositions exist.
