Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511166, here are decompositions:

3 + 511163 = 511166
13 + 511153 = 511166
43 + 511123 = 511166
79 + 511087 = 511166
109 + 511057 = 511166
127 + 511039 = 511166
223 + 510943 = 511166
277 + 510889 = 511166

Showing the first eight; more decompositions exist.
