Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755686, here are decompositions:

19 + 8755667 = 8755686
47 + 8755639 = 8755686
67 + 8755619 = 8755686
73 + 8755613 = 8755686
83 + 8755603 = 8755686
127 + 8755559 = 8755686
157 + 8755529 = 8755686
293 + 8755393 = 8755686

Showing the first eight; more decompositions exist.
