Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718188, here are decompositions:

79 + 8718109 = 8718188
97 + 8718091 = 8718188
181 + 8718007 = 8718188
229 + 8717959 = 8718188
307 + 8717881 = 8718188
331 + 8717857 = 8718188
379 + 8717809 = 8718188
397 + 8717791 = 8718188

Showing the first eight; more decompositions exist.
