Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594460, here are decompositions:

31 + 31594429 = 31594460
61 + 31594399 = 31594460
67 + 31594393 = 31594460
109 + 31594351 = 31594460
127 + 31594333 = 31594460
151 + 31594309 = 31594460
223 + 31594237 = 31594460
379 + 31594081 = 31594460

Showing the first eight; more decompositions exist.
