Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594382, here are decompositions:

31 + 31594351 = 31594382
73 + 31594309 = 31594382
109 + 31594273 = 31594382
223 + 31594159 = 31594382
439 + 31593943 = 31594382
619 + 31593763 = 31594382
661 + 31593721 = 31594382
739 + 31593643 = 31594382

Showing the first eight; more decompositions exist.
