Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627610, here are decompositions:

37 + 31627573 = 31627610
43 + 31627567 = 31627610
67 + 31627543 = 31627610
73 + 31627537 = 31627610
109 + 31627501 = 31627610
127 + 31627483 = 31627610
199 + 31627411 = 31627610
277 + 31627333 = 31627610

Showing the first eight; more decompositions exist.
