Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514122, here are decompositions:

41 + 31514081 = 31514122
179 + 31513943 = 31514122
383 + 31513739 = 31514122
401 + 31513721 = 31514122
461 + 31513661 = 31514122
509 + 31513613 = 31514122
719 + 31513403 = 31514122
863 + 31513259 = 31514122

Showing the first eight; more decompositions exist.
