Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688816, here are decompositions:

7 + 8688809 = 8688816
29 + 8688787 = 8688816
109 + 8688707 = 8688816
113 + 8688703 = 8688816
223 + 8688593 = 8688816
233 + 8688583 = 8688816
239 + 8688577 = 8688816
263 + 8688553 = 8688816

Showing the first eight; more decompositions exist.
