Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594738, here are decompositions:

11 + 31594727 = 31594738
47 + 31594691 = 31594738
191 + 31594547 = 31594738
317 + 31594421 = 31594738
467 + 31594271 = 31594738
491 + 31594247 = 31594738
587 + 31594151 = 31594738
641 + 31594097 = 31594738

Showing the first eight; more decompositions exist.
