Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616826, here are decompositions:

5 + 8616821 = 8616826
17 + 8616809 = 8616826
107 + 8616719 = 8616826
137 + 8616689 = 8616826
173 + 8616653 = 8616826
227 + 8616599 = 8616826
263 + 8616563 = 8616826
293 + 8616533 = 8616826

Showing the first eight; more decompositions exist.
