Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511456, here are decompositions:

3 + 511453 = 511456
17 + 511439 = 511456
47 + 511409 = 511456
167 + 511289 = 511456
233 + 511223 = 511456
263 + 511193 = 511456
293 + 511163 = 511456
347 + 511109 = 511456

Showing the first eight; more decompositions exist.
