Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718078, here are decompositions:

67 + 8718011 = 8718078
71 + 8718007 = 8718078
79 + 8717999 = 8718078
97 + 8717981 = 8718078
139 + 8717939 = 8718078
151 + 8717927 = 8718078
197 + 8717881 = 8718078
211 + 8717867 = 8718078

Showing the first eight; more decompositions exist.
