Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596446, here are decompositions:

43 + 31596403 = 31596446
67 + 31596379 = 31596446
139 + 31596307 = 31596446
283 + 31596163 = 31596446
379 + 31596067 = 31596446
397 + 31596049 = 31596446
439 + 31596007 = 31596446
457 + 31595989 = 31596446

Showing the first eight; more decompositions exist.
