Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718112, here are decompositions:

3 + 8718109 = 8718112
23 + 8718089 = 8718112
101 + 8718011 = 8718112
113 + 8717999 = 8718112
131 + 8717981 = 8718112
149 + 8717963 = 8718112
173 + 8717939 = 8718112
239 + 8717873 = 8718112

Showing the first eight; more decompositions exist.
