Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594984, here are decompositions:

23 + 31594961 = 31594984
53 + 31594931 = 31594984
101 + 31594883 = 31594984
107 + 31594877 = 31594984
173 + 31594811 = 31594984
227 + 31594757 = 31594984
257 + 31594727 = 31594984
293 + 31594691 = 31594984

Showing the first eight; more decompositions exist.
