Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483976, here are decompositions:

19 + 31483957 = 31483976
157 + 31483819 = 31483976
313 + 31483663 = 31483976
379 + 31483597 = 31483976
523 + 31483453 = 31483976
547 + 31483429 = 31483976
607 + 31483369 = 31483976
739 + 31483237 = 31483976

Showing the first eight; more decompositions exist.
