Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512208, here are decompositions:

41 + 512167 = 512208
61 + 512147 = 512208
71 + 512137 = 512208
107 + 512101 = 512208
149 + 512059 = 512208
197 + 512011 = 512208
199 + 512009 = 512208
211 + 511997 = 512208

Showing the first eight; more decompositions exist.
