Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509540, here are decompositions:

19 + 509521 = 509540
127 + 509413 = 509540
151 + 509389 = 509540
181 + 509359 = 509540
211 + 509329 = 509540
223 + 509317 = 509540
277 + 509263 = 509540
313 + 509227 = 509540

Showing the first eight; more decompositions exist.
