Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715870, here are decompositions:

29 + 8715841 = 8715870
83 + 8715787 = 8715870
101 + 8715769 = 8715870
109 + 8715761 = 8715870
139 + 8715731 = 8715870
151 + 8715719 = 8715870
167 + 8715703 = 8715870
173 + 8715697 = 8715870

Showing the first eight; more decompositions exist.
