Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639776, here are decompositions:

3 + 8639773 = 8639776
23 + 8639753 = 8639776
29 + 8639747 = 8639776
113 + 8639663 = 8639776
137 + 8639639 = 8639776
179 + 8639597 = 8639776
227 + 8639549 = 8639776
269 + 8639507 = 8639776

Showing the first eight; more decompositions exist.
