Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511258, here are decompositions:

47 + 511211 = 511258
89 + 511169 = 511258
107 + 511151 = 511258
149 + 511109 = 511258
197 + 511061 = 511258
239 + 511019 = 511258
257 + 511001 = 511258
269 + 510989 = 511258

Showing the first eight; more decompositions exist.
