Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688356, here are decompositions:

3 + 8688353 = 8688356
7 + 8688349 = 8688356
73 + 8688283 = 8688356
97 + 8688259 = 8688356
199 + 8688157 = 8688356
223 + 8688133 = 8688356
373 + 8687983 = 8688356
433 + 8687923 = 8688356

Showing the first eight; more decompositions exist.
