Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688290, here are decompositions:

3 + 8688287 = 8688290
7 + 8688283 = 8688290
19 + 8688271 = 8688290
31 + 8688259 = 8688290
157 + 8688133 = 8688290
181 + 8688109 = 8688290
223 + 8688067 = 8688290
277 + 8688013 = 8688290

Showing the first eight; more decompositions exist.
