Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594864, here are decompositions:

3 + 31594861 = 31594864
53 + 31594811 = 31594864
107 + 31594757 = 31594864
137 + 31594727 = 31594864
173 + 31594691 = 31594864
251 + 31594613 = 31594864
281 + 31594583 = 31594864
311 + 31594553 = 31594864

Showing the first eight; more decompositions exist.
