Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467384, here are decompositions:

17 + 31467367 = 31467384
37 + 31467347 = 31467384
73 + 31467311 = 31467384
83 + 31467301 = 31467384
181 + 31467203 = 31467384
227 + 31467157 = 31467384
251 + 31467133 = 31467384
257 + 31467127 = 31467384

Showing the first eight; more decompositions exist.
