Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718130, here are decompositions:

17 + 8718113 = 8718130
41 + 8718089 = 8718130
131 + 8717999 = 8718130
137 + 8717993 = 8718130
149 + 8717981 = 8718130
167 + 8717963 = 8718130
191 + 8717939 = 8718130
257 + 8717873 = 8718130

Showing the first eight; more decompositions exist.
