Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627140, here are decompositions:

7 + 31627133 = 31627140
19 + 31627121 = 31627140
67 + 31627073 = 31627140
71 + 31627069 = 31627140
89 + 31627051 = 31627140
107 + 31627033 = 31627140
113 + 31627027 = 31627140
163 + 31626977 = 31627140

Showing the first eight; more decompositions exist.
