Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467430, here are decompositions:

11 + 31467419 = 31467430
41 + 31467389 = 31467430
83 + 31467347 = 31467430
101 + 31467329 = 31467430
179 + 31467251 = 31467430
227 + 31467203 = 31467430
263 + 31467167 = 31467430
347 + 31467083 = 31467430

Showing the first eight; more decompositions exist.
