Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716218, here are decompositions:

11 + 8716207 = 8716218
31 + 8716187 = 8716218
37 + 8716181 = 8716218
59 + 8716159 = 8716218
67 + 8716151 = 8716218
109 + 8716109 = 8716218
149 + 8716069 = 8716218
157 + 8716061 = 8716218

Showing the first eight; more decompositions exist.
