Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484660, here are decompositions:

13 + 31484647 = 31484660
43 + 31484617 = 31484660
127 + 31484533 = 31484660
157 + 31484503 = 31484660
199 + 31484461 = 31484660
211 + 31484449 = 31484660
283 + 31484377 = 31484660
307 + 31484353 = 31484660

Showing the first eight; more decompositions exist.
