Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594634, here are decompositions:

7 + 31594627 = 31594634
37 + 31594597 = 31594634
61 + 31594573 = 31594634
241 + 31594393 = 31594634
283 + 31594351 = 31594634
397 + 31594237 = 31594634
571 + 31594063 = 31594634
691 + 31593943 = 31594634

Showing the first eight; more decompositions exist.
