Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450294, here are decompositions:

3 + 31450291 = 31450294
23 + 31450271 = 31450294
47 + 31450247 = 31450294
131 + 31450163 = 31450294
191 + 31450103 = 31450294
233 + 31450061 = 31450294
251 + 31450043 = 31450294
263 + 31450031 = 31450294

Showing the first eight; more decompositions exist.
