Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621656, here are decompositions:

3 + 8621653 = 8621656
47 + 8621609 = 8621656
179 + 8621477 = 8621656
227 + 8621429 = 8621656
317 + 8621339 = 8621656
347 + 8621309 = 8621656
419 + 8621237 = 8621656
443 + 8621213 = 8621656

Showing the first eight; more decompositions exist.
