Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513234, here are decompositions:

41 + 31513193 = 31513234
47 + 31513187 = 31513234
197 + 31513037 = 31513234
227 + 31513007 = 31513234
503 + 31512731 = 31513234
617 + 31512617 = 31513234
647 + 31512587 = 31513234
677 + 31512557 = 31513234

Showing the first eight; more decompositions exist.
