Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755782, here are decompositions:

41 + 8755741 = 8755782
53 + 8755729 = 8755782
59 + 8755723 = 8755782
71 + 8755711 = 8755782
83 + 8755699 = 8755782
163 + 8755619 = 8755782
179 + 8755603 = 8755782
181 + 8755601 = 8755782

Showing the first eight; more decompositions exist.
