Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594586, here are decompositions:

3 + 31594583 = 31594586
7 + 31594579 = 31594586
13 + 31594573 = 31594586
97 + 31594489 = 31594586
157 + 31594429 = 31594586
193 + 31594393 = 31594586
277 + 31594309 = 31594586
313 + 31594273 = 31594586

Showing the first eight; more decompositions exist.
