Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627154, here are decompositions:

3 + 31627151 = 31627154
103 + 31627051 = 31627154
127 + 31627027 = 31627154
211 + 31626943 = 31627154
271 + 31626883 = 31627154
313 + 31626841 = 31627154
367 + 31626787 = 31627154
463 + 31626691 = 31627154

Showing the first eight; more decompositions exist.
