Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511384, here are decompositions:

23 + 511361 = 511384
47 + 511337 = 511384
173 + 511211 = 511384
191 + 511193 = 511384
233 + 511151 = 511384
383 + 511001 = 511384
443 + 510941 = 511384
557 + 510827 = 511384

Showing the first eight; more decompositions exist.
