Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484876, here are decompositions:

13 + 31484863 = 31484876
37 + 31484839 = 31484876
79 + 31484797 = 31484876
229 + 31484647 = 31484876
307 + 31484569 = 31484876
373 + 31484503 = 31484876
463 + 31484413 = 31484876
499 + 31484377 = 31484876

Showing the first eight; more decompositions exist.
