Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461212, here are decompositions:

19 + 31461193 = 31461212
31 + 31461181 = 31461212
163 + 31461049 = 31461212
199 + 31461013 = 31461212
241 + 31460971 = 31461212
283 + 31460929 = 31461212
373 + 31460839 = 31461212
379 + 31460833 = 31461212

Showing the first eight; more decompositions exist.
