Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486586, here are decompositions:

37 + 31486549 = 31486586
163 + 31486423 = 31486586
193 + 31486393 = 31486586
199 + 31486387 = 31486586
283 + 31486303 = 31486586
457 + 31486129 = 31486586
463 + 31486123 = 31486586
499 + 31486087 = 31486586

Showing the first eight; more decompositions exist.
