Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718306, here are decompositions:

5 + 8718301 = 8718306
29 + 8718277 = 8718306
59 + 8718247 = 8718306
89 + 8718217 = 8718306
109 + 8718197 = 8718306
193 + 8718113 = 8718306
197 + 8718109 = 8718306
263 + 8718043 = 8718306

Showing the first eight; more decompositions exist.
