Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512286, here are decompositions:

17 + 512269 = 512286
37 + 512249 = 512286
79 + 512207 = 512286
139 + 512147 = 512286
149 + 512137 = 512286
193 + 512093 = 512286
227 + 512059 = 512286
239 + 512047 = 512286

Showing the first eight; more decompositions exist.
