Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484522, here are decompositions:

19 + 31484503 = 31484522
61 + 31484461 = 31484522
73 + 31484449 = 31484522
109 + 31484413 = 31484522
163 + 31484359 = 31484522
241 + 31484281 = 31484522
283 + 31484239 = 31484522
313 + 31484209 = 31484522

Showing the first eight; more decompositions exist.
