Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483712, here are decompositions:

163 + 31483549 = 31483712
241 + 31483471 = 31483712
283 + 31483429 = 31483712
499 + 31483213 = 31483712
619 + 31483093 = 31483712
643 + 31483069 = 31483712
661 + 31483051 = 31483712
709 + 31483003 = 31483712

Showing the first eight; more decompositions exist.
