Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512238, here are decompositions:

31 + 512207 = 512238
71 + 512167 = 512238
101 + 512137 = 512238
137 + 512101 = 512238
179 + 512059 = 512238
191 + 512047 = 512238
227 + 512011 = 512238
229 + 512009 = 512238

Showing the first eight; more decompositions exist.
