Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476370, here are decompositions:

17 + 31476353 = 31476370
53 + 31476317 = 31476370
131 + 31476239 = 31476370
227 + 31476143 = 31476370
251 + 31476119 = 31476370
257 + 31476113 = 31476370
311 + 31476059 = 31476370
353 + 31476017 = 31476370

Showing the first eight; more decompositions exist.
