Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717828, here are decompositions:

19 + 8717809 = 8717828
37 + 8717791 = 8717828
61 + 8717767 = 8717828
79 + 8717749 = 8717828
139 + 8717689 = 8717828
151 + 8717677 = 8717828
271 + 8717557 = 8717828
277 + 8717551 = 8717828

Showing the first eight; more decompositions exist.
