Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666300, here are decompositions:

31 + 8666269 = 8666300
127 + 8666173 = 8666300
163 + 8666137 = 8666300
241 + 8666059 = 8666300
277 + 8666023 = 8666300
283 + 8666017 = 8666300
367 + 8665933 = 8666300
523 + 8665777 = 8666300

Showing the first eight; more decompositions exist.
