Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484744, here are decompositions:

3 + 31484741 = 31484744
97 + 31484647 = 31484744
127 + 31484617 = 31484744
211 + 31484533 = 31484744
241 + 31484503 = 31484744
283 + 31484461 = 31484744
331 + 31484413 = 31484744
367 + 31484377 = 31484744

Showing the first eight; more decompositions exist.
