Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688316, here are decompositions:

5 + 8688311 = 8688316
17 + 8688299 = 8688316
29 + 8688287 = 8688316
107 + 8688209 = 8688316
113 + 8688203 = 8688316
149 + 8688167 = 8688316
173 + 8688143 = 8688316
233 + 8688083 = 8688316

Showing the first eight; more decompositions exist.
