Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755728, here are decompositions:

5 + 8755723 = 8755728
17 + 8755711 = 8755728
29 + 8755699 = 8755728
61 + 8755667 = 8755728
89 + 8755639 = 8755728
109 + 8755619 = 8755728
127 + 8755601 = 8755728
199 + 8755529 = 8755728

Showing the first eight; more decompositions exist.
