Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594918, here are decompositions:

11 + 31594907 = 31594918
41 + 31594877 = 31594918
107 + 31594811 = 31594918
149 + 31594769 = 31594918
191 + 31594727 = 31594918
227 + 31594691 = 31594918
587 + 31594331 = 31594918
647 + 31594271 = 31594918

Showing the first eight; more decompositions exist.
