Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484684, here are decompositions:

37 + 31484647 = 31484684
67 + 31484617 = 31484684
151 + 31484533 = 31484684
181 + 31484503 = 31484684
223 + 31484461 = 31484684
271 + 31484413 = 31484684
307 + 31484377 = 31484684
331 + 31484353 = 31484684

Showing the first eight; more decompositions exist.
