Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493514, here are decompositions:

37 + 31493477 = 31493514
47 + 31493467 = 31493514
67 + 31493447 = 31493514
71 + 31493443 = 31493514
137 + 31493377 = 31493514
167 + 31493347 = 31493514
191 + 31493323 = 31493514
193 + 31493321 = 31493514

Showing the first eight; more decompositions exist.
