Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483724, here are decompositions:

61 + 31483663 = 31483724
127 + 31483597 = 31483724
271 + 31483453 = 31483724
277 + 31483447 = 31483724
373 + 31483351 = 31483724
397 + 31483327 = 31483724
463 + 31483261 = 31483724
487 + 31483237 = 31483724

Showing the first eight; more decompositions exist.
