Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715786, here are decompositions:

7 + 8715779 = 8715786
17 + 8715769 = 8715786
67 + 8715719 = 8715786
83 + 8715703 = 8715786
89 + 8715697 = 8715786
113 + 8715673 = 8715786
127 + 8715659 = 8715786
137 + 8715649 = 8715786

Showing the first eight; more decompositions exist.
