Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597466, here are decompositions:

13 + 31597453 = 31597466
223 + 31597243 = 31597466
337 + 31597129 = 31597466
367 + 31597099 = 31597466
463 + 31597003 = 31597466
577 + 31596889 = 31597466
619 + 31596847 = 31597466
673 + 31596793 = 31597466

Showing the first eight; more decompositions exist.
