Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716818, here are decompositions:

59 + 8716759 = 8716818
109 + 8716709 = 8716818
127 + 8716691 = 8716818
139 + 8716679 = 8716818
157 + 8716661 = 8716818
179 + 8716639 = 8716818
191 + 8716627 = 8716818
199 + 8716619 = 8716818

Showing the first eight; more decompositions exist.
