Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718828, here are decompositions:

5 + 8718823 = 8718828
17 + 8718811 = 8718828
29 + 8718799 = 8718828
31 + 8718797 = 8718828
71 + 8718757 = 8718828
101 + 8718727 = 8718828
179 + 8718649 = 8718828
227 + 8718601 = 8718828

Showing the first eight; more decompositions exist.
