Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509572, here are decompositions:

3 + 509569 = 509572
23 + 509549 = 509572
29 + 509543 = 509572
59 + 509513 = 509572
131 + 509441 = 509572
179 + 509393 = 509572
449 + 509123 = 509572
509 + 509063 = 509572

Showing the first eight; more decompositions exist.
