Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450374, here are decompositions:

5 + 31450369 = 31450374
23 + 31450351 = 31450374
61 + 31450313 = 31450374
83 + 31450291 = 31450374
103 + 31450271 = 31450374
127 + 31450247 = 31450374
157 + 31450217 = 31450374
167 + 31450207 = 31450374

Showing the first eight; more decompositions exist.
