Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484612, here are decompositions:

43 + 31484569 = 31484612
79 + 31484533 = 31484612
109 + 31484503 = 31484612
151 + 31484461 = 31484612
163 + 31484449 = 31484612
199 + 31484413 = 31484612
331 + 31484281 = 31484612
373 + 31484239 = 31484612

Showing the first eight; more decompositions exist.
