Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755878, here are decompositions:

29 + 8755849 = 8755878
37 + 8755841 = 8755878
59 + 8755819 = 8755878
67 + 8755811 = 8755878
97 + 8755781 = 8755878
137 + 8755741 = 8755878
149 + 8755729 = 8755878
167 + 8755711 = 8755878

Showing the first eight; more decompositions exist.
