Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466968, here are decompositions:

17 + 31466951 = 31466968
101 + 31466867 = 31466968
311 + 31466657 = 31466968
419 + 31466549 = 31466968
587 + 31466381 = 31466968
641 + 31466327 = 31466968
677 + 31466291 = 31466968
719 + 31466249 = 31466968

Showing the first eight; more decompositions exist.
