Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486502, here are decompositions:

79 + 31486423 = 31486502
109 + 31486393 = 31486502
163 + 31486339 = 31486502
199 + 31486303 = 31486502
373 + 31486129 = 31486502
379 + 31486123 = 31486502
571 + 31485931 = 31486502
613 + 31485889 = 31486502

Showing the first eight; more decompositions exist.
