Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484852, here are decompositions:

13 + 31484839 = 31484852
31 + 31484821 = 31484852
283 + 31484569 = 31484852
349 + 31484503 = 31484852
439 + 31484413 = 31484852
499 + 31484353 = 31484852
571 + 31484281 = 31484852
613 + 31484239 = 31484852

Showing the first eight; more decompositions exist.
