Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509556, here are decompositions:

7 + 509549 = 509556
13 + 509543 = 509556
43 + 509513 = 509556
79 + 509477 = 509556
107 + 509449 = 509556
127 + 509429 = 509556
139 + 509417 = 509556
163 + 509393 = 509556

Showing the first eight; more decompositions exist.
