Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509580, here are decompositions:

7 + 509573 = 509580
11 + 509569 = 509580
17 + 509563 = 509580
23 + 509557 = 509580
31 + 509549 = 509580
37 + 509543 = 509580
59 + 509521 = 509580
67 + 509513 = 509580

Showing the first eight; more decompositions exist.
