Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627634, here are decompositions:

7 + 31627627 = 31627634
61 + 31627573 = 31627634
67 + 31627567 = 31627634
97 + 31627537 = 31627634
151 + 31627483 = 31627634
223 + 31627411 = 31627634
277 + 31627357 = 31627634
331 + 31627303 = 31627634

Showing the first eight; more decompositions exist.
