Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493524, here are decompositions:

3 + 31493521 = 31493524
5 + 31493519 = 31493524
11 + 31493513 = 31493524
47 + 31493477 = 31493524
233 + 31493291 = 31493524
353 + 31493171 = 31493524
467 + 31493057 = 31493524
617 + 31492907 = 31493524

Showing the first eight; more decompositions exist.
