Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607190, here are decompositions:

37 + 31607153 = 31607190
53 + 31607137 = 31607190
89 + 31607101 = 31607190
103 + 31607087 = 31607190
151 + 31607039 = 31607190
193 + 31606997 = 31607190
211 + 31606979 = 31607190
227 + 31606963 = 31607190

Showing the first eight; more decompositions exist.
