Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483700, here are decompositions:

37 + 31483663 = 31483700
103 + 31483597 = 31483700
151 + 31483549 = 31483700
229 + 31483471 = 31483700
271 + 31483429 = 31483700
331 + 31483369 = 31483700
349 + 31483351 = 31483700
373 + 31483327 = 31483700

Showing the first eight; more decompositions exist.
