Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596398, here are decompositions:

7 + 31596391 = 31596398
19 + 31596379 = 31596398
271 + 31596127 = 31596398
277 + 31596121 = 31596398
331 + 31596067 = 31596398
349 + 31596049 = 31596398
409 + 31595989 = 31596398
727 + 31595671 = 31596398

Showing the first eight; more decompositions exist.
