Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509530, here are decompositions:

17 + 509513 = 509530
53 + 509477 = 509530
89 + 509441 = 509530
101 + 509429 = 509530
113 + 509417 = 509530
137 + 509393 = 509530
167 + 509363 = 509530
233 + 509297 = 509530

Showing the first eight; more decompositions exist.
