Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755990, here are decompositions:

17 + 8755973 = 8755990
53 + 8755937 = 8755990
101 + 8755889 = 8755990
137 + 8755853 = 8755990
149 + 8755841 = 8755990
167 + 8755823 = 8755990
179 + 8755811 = 8755990
389 + 8755601 = 8755990

Showing the first eight; more decompositions exist.
