Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627662, here are decompositions:

13 + 31627649 = 31627662
23 + 31627639 = 31627662
61 + 31627601 = 31627662
89 + 31627573 = 31627662
103 + 31627559 = 31627662
151 + 31627511 = 31627662
179 + 31627483 = 31627662
251 + 31627411 = 31627662

Showing the first eight; more decompositions exist.
