Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688318, here are decompositions:

7 + 8688311 = 8688318
19 + 8688299 = 8688318
31 + 8688287 = 8688318
47 + 8688271 = 8688318
59 + 8688259 = 8688318
97 + 8688221 = 8688318
109 + 8688209 = 8688318
151 + 8688167 = 8688318

Showing the first eight; more decompositions exist.
