Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715882, here are decompositions:

5 + 8715877 = 8715882
41 + 8715841 = 8715882
89 + 8715793 = 8715882
103 + 8715779 = 8715882
113 + 8715769 = 8715882
151 + 8715731 = 8715882
163 + 8715719 = 8715882
173 + 8715709 = 8715882

Showing the first eight; more decompositions exist.
