Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718266, here are decompositions:

19 + 8718247 = 8718266
103 + 8718163 = 8718266
157 + 8718109 = 8718266
163 + 8718103 = 8718266
223 + 8718043 = 8718266
307 + 8717959 = 8718266
397 + 8717869 = 8718266
409 + 8717857 = 8718266

Showing the first eight; more decompositions exist.
