Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509930, here are decompositions:

19 + 509911 = 509930
67 + 509863 = 509930
97 + 509833 = 509930
163 + 509767 = 509930
193 + 509737 = 509930
199 + 509731 = 509930
241 + 509689 = 509930
271 + 509659 = 509930

Showing the first eight; more decompositions exist.
