Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484486, here are decompositions:

37 + 31484449 = 31484486
73 + 31484413 = 31484486
109 + 31484377 = 31484486
127 + 31484359 = 31484486
277 + 31484209 = 31484486
283 + 31484203 = 31484486
307 + 31484179 = 31484486
727 + 31483759 = 31484486

Showing the first eight; more decompositions exist.
