Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715828, here are decompositions:

41 + 8715787 = 8715828
59 + 8715769 = 8715828
67 + 8715761 = 8715828
97 + 8715731 = 8715828
109 + 8715719 = 8715828
131 + 8715697 = 8715828
157 + 8715671 = 8715828
179 + 8715649 = 8715828

Showing the first eight; more decompositions exist.
