Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450354, here are decompositions:

3 + 31450351 = 31450354
41 + 31450313 = 31450354
83 + 31450271 = 31450354
107 + 31450247 = 31450354
137 + 31450217 = 31450354
191 + 31450163 = 31450354
251 + 31450103 = 31450354
293 + 31450061 = 31450354

Showing the first eight; more decompositions exist.
