Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645776, here are decompositions:

3 + 8645773 = 8645776
17 + 8645759 = 8645776
47 + 8645729 = 8645776
89 + 8645687 = 8645776
107 + 8645669 = 8645776
179 + 8645597 = 8645776
197 + 8645579 = 8645776
233 + 8645543 = 8645776

Showing the first eight; more decompositions exist.
