Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510256, here are decompositions:

3 + 510253 = 510256
23 + 510233 = 510256
29 + 510227 = 510256
53 + 510203 = 510256
167 + 510089 = 510256
179 + 510077 = 510256
293 + 509963 = 510256
317 + 509939 = 510256

Showing the first eight; more decompositions exist.
