Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514284, here are decompositions:

17 + 31514267 = 31514284
23 + 31514261 = 31514284
317 + 31513967 = 31514284
467 + 31513817 = 31514284
491 + 31513793 = 31514284
563 + 31513721 = 31514284
587 + 31513697 = 31514284
617 + 31513667 = 31514284

Showing the first eight; more decompositions exist.
