Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467238, here are decompositions:

71 + 31467167 = 31467238
149 + 31467089 = 31467238
167 + 31467071 = 31467238
227 + 31467011 = 31467238
239 + 31466999 = 31467238
269 + 31466969 = 31467238
389 + 31466849 = 31467238
479 + 31466759 = 31467238

Showing the first eight; more decompositions exist.
