Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720776, here are decompositions:

3 + 8720773 = 8720776
5 + 8720771 = 8720776
47 + 8720729 = 8720776
83 + 8720693 = 8720776
89 + 8720687 = 8720776
149 + 8720627 = 8720776
179 + 8720597 = 8720776
263 + 8720513 = 8720776

Showing the first eight; more decompositions exist.
