Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467148, here are decompositions:

59 + 31467089 = 31467148
137 + 31467011 = 31467148
149 + 31466999 = 31467148
179 + 31466969 = 31467148
197 + 31466951 = 31467148
281 + 31466867 = 31467148
389 + 31466759 = 31467148
491 + 31466657 = 31467148

Showing the first eight; more decompositions exist.
