Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720676, here are decompositions:

5 + 8720671 = 8720676
47 + 8720629 = 8720676
53 + 8720623 = 8720676
59 + 8720617 = 8720676
79 + 8720597 = 8720676
163 + 8720513 = 8720676
179 + 8720497 = 8720676
193 + 8720483 = 8720676

Showing the first eight; more decompositions exist.
