Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594840, here are decompositions:

29 + 31594811 = 31594840
41 + 31594799 = 31594840
71 + 31594769 = 31594840
83 + 31594757 = 31594840
113 + 31594727 = 31594840
149 + 31594691 = 31594840
227 + 31594613 = 31594840
257 + 31594583 = 31594840

Showing the first eight; more decompositions exist.
