Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509620, here are decompositions:

17 + 509603 = 509620
29 + 509591 = 509620
47 + 509573 = 509620
71 + 509549 = 509620
107 + 509513 = 509620
179 + 509441 = 509620
191 + 509429 = 509620
227 + 509393 = 509620

Showing the first eight; more decompositions exist.
