Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595134, here are decompositions:

71 + 31595063 = 31595134
113 + 31595021 = 31595134
173 + 31594961 = 31595134
227 + 31594907 = 31595134
251 + 31594883 = 31595134
257 + 31594877 = 31595134
443 + 31594691 = 31595134
521 + 31594613 = 31595134

Showing the first eight; more decompositions exist.
