Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688826, here are decompositions:

17 + 8688809 = 8688826
197 + 8688629 = 8688826
233 + 8688593 = 8688826
257 + 8688569 = 8688826
269 + 8688557 = 8688826
389 + 8688437 = 8688826
617 + 8688209 = 8688826
659 + 8688167 = 8688826

Showing the first eight; more decompositions exist.
