Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718168, here are decompositions:

5 + 8718163 = 8718168
59 + 8718109 = 8718168
71 + 8718097 = 8718168
79 + 8718089 = 8718168
157 + 8718011 = 8718168
181 + 8717987 = 8718168
229 + 8717939 = 8718168
241 + 8717927 = 8718168

Showing the first eight; more decompositions exist.
