Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716828, here are decompositions:

11 + 8716817 = 8716828
59 + 8716769 = 8716828
101 + 8716727 = 8716828
137 + 8716691 = 8716828
149 + 8716679 = 8716828
167 + 8716661 = 8716828
359 + 8716469 = 8716828
389 + 8716439 = 8716828

Showing the first eight; more decompositions exist.
