Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509852, here are decompositions:

19 + 509833 = 509852
163 + 509689 = 509852
193 + 509659 = 509852
199 + 509653 = 509852
229 + 509623 = 509852
271 + 509581 = 509852
283 + 509569 = 509852
331 + 509521 = 509852

Showing the first eight; more decompositions exist.
