Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627618, here are decompositions:

17 + 31627601 = 31627618
41 + 31627577 = 31627618
59 + 31627559 = 31627618
107 + 31627511 = 31627618
227 + 31627391 = 31627618
401 + 31627217 = 31627618
467 + 31627151 = 31627618
641 + 31626977 = 31627618

Showing the first eight; more decompositions exist.
