Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718656, here are decompositions:

7 + 8718649 = 8718656
229 + 8718427 = 8718656
307 + 8718349 = 8718656
313 + 8718343 = 8718656
379 + 8718277 = 8718656
409 + 8718247 = 8718656
439 + 8718217 = 8718656
547 + 8718109 = 8718656

Showing the first eight; more decompositions exist.
