Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486412, here are decompositions:

19 + 31486393 = 31486412
73 + 31486339 = 31486412
109 + 31486303 = 31486412
211 + 31486201 = 31486412
283 + 31486129 = 31486412
379 + 31486033 = 31486412
439 + 31485973 = 31486412
523 + 31485889 = 31486412

Showing the first eight; more decompositions exist.
