Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546522, here are decompositions:

53 + 31546469 = 31546522
71 + 31546451 = 31546522
101 + 31546421 = 31546522
173 + 31546349 = 31546522
239 + 31546283 = 31546522
503 + 31546019 = 31546522
509 + 31546013 = 31546522
563 + 31545959 = 31546522

Showing the first eight; more decompositions exist.
