Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467178, here are decompositions:

11 + 31467167 = 31467178
89 + 31467089 = 31467178
107 + 31467071 = 31467178
167 + 31467011 = 31467178
179 + 31466999 = 31467178
227 + 31466951 = 31467178
311 + 31466867 = 31467178
419 + 31466759 = 31467178

Showing the first eight; more decompositions exist.
