Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483676, here are decompositions:

13 + 31483663 = 31483676
79 + 31483597 = 31483676
127 + 31483549 = 31483676
223 + 31483453 = 31483676
229 + 31483447 = 31483676
307 + 31483369 = 31483676
349 + 31483327 = 31483676
439 + 31483237 = 31483676

Showing the first eight; more decompositions exist.
