Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509516, here are decompositions:

3 + 509513 = 509516
67 + 509449 = 509516
103 + 509413 = 509516
127 + 509389 = 509516
157 + 509359 = 509516
199 + 509317 = 509516
223 + 509293 = 509516
229 + 509287 = 509516

Showing the first eight; more decompositions exist.
