Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755812, here are decompositions:

31 + 8755781 = 8755812
71 + 8755741 = 8755812
83 + 8755729 = 8755812
89 + 8755723 = 8755812
101 + 8755711 = 8755812
113 + 8755699 = 8755812
173 + 8755639 = 8755812
193 + 8755619 = 8755812

Showing the first eight; more decompositions exist.
