Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594646, here are decompositions:

19 + 31594627 = 31594646
37 + 31594609 = 31594646
67 + 31594579 = 31594646
73 + 31594573 = 31594646
157 + 31594489 = 31594646
313 + 31594333 = 31594646
337 + 31594309 = 31594646
373 + 31594273 = 31594646

Showing the first eight; more decompositions exist.
