Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484676, here are decompositions:

29 + 31484647 = 31484676
59 + 31484617 = 31484676
107 + 31484569 = 31484676
163 + 31484513 = 31484676
173 + 31484503 = 31484676
227 + 31484449 = 31484676
263 + 31484413 = 31484676
313 + 31484363 = 31484676

Showing the first eight; more decompositions exist.
