Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467588, here are decompositions:

17 + 31467571 = 31467588
29 + 31467559 = 31467588
37 + 31467551 = 31467588
79 + 31467509 = 31467588
107 + 31467481 = 31467588
151 + 31467437 = 31467588
157 + 31467431 = 31467588
199 + 31467389 = 31467588

Showing the first eight; more decompositions exist.
