Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509238, here are decompositions:

11 + 509227 = 509238
17 + 509221 = 509238
89 + 509149 = 509238
101 + 509137 = 509238
137 + 509101 = 509238
151 + 509087 = 509238
167 + 509071 = 509238
211 + 509027 = 509238

Showing the first eight; more decompositions exist.
