Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463612, here are decompositions:

79 + 31463533 = 31463612
223 + 31463389 = 31463612
283 + 31463329 = 31463612
331 + 31463281 = 31463612
409 + 31463203 = 31463612
643 + 31462969 = 31463612
853 + 31462759 = 31463612
883 + 31462729 = 31463612

Showing the first eight; more decompositions exist.
