Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511486, here are decompositions:

23 + 511463 = 511486
29 + 511457 = 511486
47 + 511439 = 511486
149 + 511337 = 511486
197 + 511289 = 511486
263 + 511223 = 511486
293 + 511193 = 511486
317 + 511169 = 511486

Showing the first eight; more decompositions exist.
