Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718156, here are decompositions:

43 + 8718113 = 8718156
47 + 8718109 = 8718156
53 + 8718103 = 8718156
59 + 8718097 = 8718156
67 + 8718089 = 8718156
113 + 8718043 = 8718156
149 + 8718007 = 8718156
157 + 8717999 = 8718156

Showing the first eight; more decompositions exist.
