Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688312, here are decompositions:

13 + 8688299 = 8688312
29 + 8688283 = 8688312
41 + 8688271 = 8688312
53 + 8688259 = 8688312
103 + 8688209 = 8688312
109 + 8688203 = 8688312
151 + 8688161 = 8688312
179 + 8688133 = 8688312

Showing the first eight; more decompositions exist.
