Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627134, here are decompositions:

13 + 31627121 = 31627134
43 + 31627091 = 31627134
61 + 31627073 = 31627134
83 + 31627051 = 31627134
101 + 31627033 = 31627134
107 + 31627027 = 31627134
127 + 31627007 = 31627134
157 + 31626977 = 31627134

Showing the first eight; more decompositions exist.
