Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688266, here are decompositions:

7 + 8688259 = 8688266
109 + 8688157 = 8688266
157 + 8688109 = 8688266
199 + 8688067 = 8688266
283 + 8687983 = 8688266
313 + 8687953 = 8688266
337 + 8687929 = 8688266
439 + 8687827 = 8688266

Showing the first eight; more decompositions exist.
