Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594664, here are decompositions:

37 + 31594627 = 31594664
67 + 31594597 = 31594664
163 + 31594501 = 31594664
271 + 31594393 = 31594664
313 + 31594351 = 31594664
331 + 31594333 = 31594664
601 + 31594063 = 31594664
727 + 31593937 = 31594664

Showing the first eight; more decompositions exist.
