Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518166, here are decompositions:

7 + 518159 = 518166
13 + 518153 = 518166
29 + 518137 = 518166
37 + 518129 = 518166
43 + 518123 = 518166
53 + 518113 = 518166
67 + 518099 = 518166
83 + 518083 = 518166

Showing the first eight; more decompositions exist.
