Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492426, here are decompositions:

3 + 31492423 = 31492426
5 + 31492421 = 31492426
23 + 31492403 = 31492426
89 + 31492337 = 31492426
107 + 31492319 = 31492426
149 + 31492277 = 31492426
167 + 31492259 = 31492426
263 + 31492163 = 31492426

Showing the first eight; more decompositions exist.
