Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594494, here are decompositions:

5 + 31594489 = 31594494
31 + 31594463 = 31594494
73 + 31594421 = 31594494
101 + 31594393 = 31594494
163 + 31594331 = 31594494
223 + 31594271 = 31594494
257 + 31594237 = 31594494
331 + 31594163 = 31594494

Showing the first eight; more decompositions exist.
