Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484126, here are decompositions:

67 + 31484059 = 31484126
199 + 31483927 = 31484126
307 + 31483819 = 31484126
337 + 31483789 = 31484126
367 + 31483759 = 31484126
463 + 31483663 = 31484126
577 + 31483549 = 31484126
673 + 31483453 = 31484126

Showing the first eight; more decompositions exist.
