Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716878, here are decompositions:

17 + 8716861 = 8716878
59 + 8716819 = 8716878
61 + 8716817 = 8716878
109 + 8716769 = 8716878
151 + 8716727 = 8716878
199 + 8716679 = 8716878
239 + 8716639 = 8716878
251 + 8716627 = 8716878

Showing the first eight; more decompositions exist.
