Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467232, here are decompositions:

3 + 31467229 = 31467232
29 + 31467203 = 31467232
149 + 31467083 = 31467232
233 + 31466999 = 31467232
239 + 31466993 = 31467232
263 + 31466969 = 31467232
281 + 31466951 = 31467232
359 + 31466873 = 31467232

Showing the first eight; more decompositions exist.
