Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512166, here are decompositions:

19 + 512147 = 512166
29 + 512137 = 512166
73 + 512093 = 512166
107 + 512059 = 512166
157 + 512009 = 512166
227 + 511939 = 512166
233 + 511933 = 512166
257 + 511909 = 512166

Showing the first eight; more decompositions exist.
