Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493716, here are decompositions:

5 + 31493711 = 31493716
197 + 31493519 = 31493716
239 + 31493477 = 31493716
269 + 31493447 = 31493716
467 + 31493249 = 31493716
563 + 31493153 = 31493716
647 + 31493069 = 31493716
659 + 31493057 = 31493716

Showing the first eight; more decompositions exist.
