Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718728, here are decompositions:

19 + 8718709 = 8718728
79 + 8718649 = 8718728
127 + 8718601 = 8718728
157 + 8718571 = 8718728
241 + 8718487 = 8718728
379 + 8718349 = 8718728
457 + 8718271 = 8718728
619 + 8718109 = 8718728

Showing the first eight; more decompositions exist.
