Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716668, here are decompositions:

5 + 8716663 = 8716668
7 + 8716661 = 8716668
29 + 8716639 = 8716668
41 + 8716627 = 8716668
89 + 8716579 = 8716668
101 + 8716567 = 8716668
137 + 8716531 = 8716668
179 + 8716489 = 8716668

Showing the first eight; more decompositions exist.
