Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509528, here are decompositions:

7 + 509521 = 509528
79 + 509449 = 509528
139 + 509389 = 509528
199 + 509329 = 509528
211 + 509317 = 509528
241 + 509287 = 509528
307 + 509221 = 509528
379 + 509149 = 509528

Showing the first eight; more decompositions exist.
