Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718318, here are decompositions:

5 + 8718313 = 8718318
17 + 8718301 = 8718318
41 + 8718277 = 8718318
47 + 8718271 = 8718318
67 + 8718251 = 8718318
71 + 8718247 = 8718318
97 + 8718221 = 8718318
101 + 8718217 = 8718318

Showing the first eight; more decompositions exist.
