Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467310, here are decompositions:

59 + 31467251 = 31467310
107 + 31467203 = 31467310
227 + 31467083 = 31467310
239 + 31467071 = 31467310
311 + 31466999 = 31467310
317 + 31466993 = 31467310
359 + 31466951 = 31467310
443 + 31466867 = 31467310

Showing the first eight; more decompositions exist.
