Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594816, here are decompositions:

3 + 31594813 = 31594816
5 + 31594811 = 31594816
17 + 31594799 = 31594816
47 + 31594769 = 31594816
59 + 31594757 = 31594816
89 + 31594727 = 31594816
233 + 31594583 = 31594816
263 + 31594553 = 31594816

Showing the first eight; more decompositions exist.
