Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726290, here are decompositions:

17 + 8726273 = 8726290
47 + 8726243 = 8726290
149 + 8726141 = 8726290
197 + 8726093 = 8726290
227 + 8726063 = 8726290
239 + 8726051 = 8726290
263 + 8726027 = 8726290
269 + 8726021 = 8726290

Showing the first eight; more decompositions exist.
