Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450134, here are decompositions:

17 + 31450117 = 31450134
31 + 31450103 = 31450134
41 + 31450093 = 31450134
73 + 31450061 = 31450134
101 + 31450033 = 31450134
103 + 31450031 = 31450134
113 + 31450021 = 31450134
167 + 31449967 = 31450134

Showing the first eight; more decompositions exist.
