Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460966, here are decompositions:

37 + 31460929 = 31460966
127 + 31460839 = 31460966
157 + 31460809 = 31460966
223 + 31460743 = 31460966
457 + 31460509 = 31460966
619 + 31460347 = 31460966
673 + 31460293 = 31460966
769 + 31460197 = 31460966

Showing the first eight; more decompositions exist.
