Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627182, here are decompositions:

31 + 31627151 = 31627182
61 + 31627121 = 31627182
109 + 31627073 = 31627182
113 + 31627069 = 31627182
131 + 31627051 = 31627182
149 + 31627033 = 31627182
239 + 31626943 = 31627182
283 + 31626899 = 31627182

Showing the first eight; more decompositions exist.
