Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627130, here are decompositions:

61 + 31627069 = 31627130
79 + 31627051 = 31627130
97 + 31627033 = 31627130
103 + 31627027 = 31627130
151 + 31626979 = 31627130
163 + 31626967 = 31627130
421 + 31626709 = 31627130
439 + 31626691 = 31627130

Showing the first eight; more decompositions exist.
