Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454912, here are decompositions:

3 + 31454909 = 31454912
31 + 31454881 = 31454912
103 + 31454809 = 31454912
211 + 31454701 = 31454912
523 + 31454389 = 31454912
691 + 31454221 = 31454912
751 + 31454161 = 31454912
829 + 31454083 = 31454912

Showing the first eight; more decompositions exist.
