Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688656, here are decompositions:

43 + 8688613 = 8688656
73 + 8688583 = 8688656
79 + 8688577 = 8688656
103 + 8688553 = 8688656
307 + 8688349 = 8688656
373 + 8688283 = 8688656
397 + 8688259 = 8688656
499 + 8688157 = 8688656

Showing the first eight; more decompositions exist.
