Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484688, here are decompositions:

41 + 31484647 = 31484688
61 + 31484627 = 31484688
71 + 31484617 = 31484688
227 + 31484461 = 31484688
239 + 31484449 = 31484688
271 + 31484417 = 31484688
311 + 31484377 = 31484688
349 + 31484339 = 31484688

Showing the first eight; more decompositions exist.
