Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688512, here are decompositions:

43 + 8688469 = 8688512
103 + 8688409 = 8688512
163 + 8688349 = 8688512
229 + 8688283 = 8688512
241 + 8688271 = 8688512
379 + 8688133 = 8688512
499 + 8688013 = 8688512
601 + 8687911 = 8688512

Showing the first eight; more decompositions exist.
