Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516234, here are decompositions:

131 + 31516103 = 31516234
173 + 31516061 = 31516234
227 + 31516007 = 31516234
293 + 31515941 = 31516234
353 + 31515881 = 31516234
467 + 31515767 = 31516234
557 + 31515677 = 31516234
587 + 31515647 = 31516234

Showing the first eight; more decompositions exist.
