Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483512, here are decompositions:

19 + 31483493 = 31483512
41 + 31483471 = 31483512
43 + 31483469 = 31483512
59 + 31483453 = 31483512
79 + 31483433 = 31483512
83 + 31483429 = 31483512
199 + 31483313 = 31483512
251 + 31483261 = 31483512

Showing the first eight; more decompositions exist.
