Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594358, here are decompositions:

7 + 31594351 = 31594358
199 + 31594159 = 31594358
277 + 31594081 = 31594358
421 + 31593937 = 31594358
457 + 31593901 = 31594358
571 + 31593787 = 31594358
727 + 31593631 = 31594358
751 + 31593607 = 31594358

Showing the first eight; more decompositions exist.
