Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596458, here are decompositions:

67 + 31596391 = 31596458
79 + 31596379 = 31596458
151 + 31596307 = 31596458
307 + 31596151 = 31596458
331 + 31596127 = 31596458
337 + 31596121 = 31596458
409 + 31596049 = 31596458
577 + 31595881 = 31596458

Showing the first eight; more decompositions exist.
