Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519922, here are decompositions:

3 + 31519919 = 31519922
13 + 31519909 = 31519922
79 + 31519843 = 31519922
139 + 31519783 = 31519922
211 + 31519711 = 31519922
223 + 31519699 = 31519922
439 + 31519483 = 31519922
463 + 31519459 = 31519922

Showing the first eight; more decompositions exist.
