Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476212, here are decompositions:

43 + 31476169 = 31476212
139 + 31476073 = 31476212
181 + 31476031 = 31476212
199 + 31476013 = 31476212
283 + 31475929 = 31476212
433 + 31475779 = 31476212
463 + 31475749 = 31476212
499 + 31475713 = 31476212

Showing the first eight; more decompositions exist.
