Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486922, here are decompositions:

199 + 31486723 = 31486922
211 + 31486711 = 31486922
283 + 31486639 = 31486922
373 + 31486549 = 31486922
499 + 31486423 = 31486922
619 + 31486303 = 31486922
991 + 31485931 = 31486922
1033 + 31485889 = 31486922

Showing the first eight; more decompositions exist.
