Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627234, here are decompositions:

17 + 31627217 = 31627234
83 + 31627151 = 31627234
101 + 31627133 = 31627234
113 + 31627121 = 31627234
227 + 31627007 = 31627234
257 + 31626977 = 31627234
467 + 31626767 = 31627234
677 + 31626557 = 31627234

Showing the first eight; more decompositions exist.
