Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715858, here are decompositions:

17 + 8715841 = 8715858
71 + 8715787 = 8715858
79 + 8715779 = 8715858
89 + 8715769 = 8715858
97 + 8715761 = 8715858
127 + 8715731 = 8715858
139 + 8715719 = 8715858
149 + 8715709 = 8715858

Showing the first eight; more decompositions exist.
