Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716188, here are decompositions:

7 + 8716181 = 8716188
29 + 8716159 = 8716188
37 + 8716151 = 8716188
79 + 8716109 = 8716188
127 + 8716061 = 8716188
149 + 8716039 = 8716188
167 + 8716021 = 8716188
181 + 8716007 = 8716188

Showing the first eight; more decompositions exist.
