Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595164, here are decompositions:

23 + 31595141 = 31595164
101 + 31595063 = 31595164
173 + 31594991 = 31595164
233 + 31594931 = 31595164
257 + 31594907 = 31595164
281 + 31594883 = 31595164
353 + 31594811 = 31595164
617 + 31594547 = 31595164

Showing the first eight; more decompositions exist.
