Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718672, here are decompositions:

23 + 8718649 = 8718672
71 + 8718601 = 8718672
101 + 8718571 = 8718672
181 + 8718491 = 8718672
211 + 8718461 = 8718672
233 + 8718439 = 8718672
241 + 8718431 = 8718672
271 + 8718401 = 8718672

Showing the first eight; more decompositions exist.
