Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627158, here are decompositions:

7 + 31627151 = 31627158
37 + 31627121 = 31627158
67 + 31627091 = 31627158
89 + 31627069 = 31627158
107 + 31627051 = 31627158
131 + 31627027 = 31627158
151 + 31627007 = 31627158
179 + 31626979 = 31627158

Showing the first eight; more decompositions exist.
