Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594256, here are decompositions:

19 + 31594237 = 31594256
97 + 31594159 = 31594256
193 + 31594063 = 31594256
313 + 31593943 = 31594256
613 + 31593643 = 31594256
643 + 31593613 = 31594256
739 + 31593517 = 31594256
1063 + 31593193 = 31594256

Showing the first eight; more decompositions exist.
