Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509942, here are decompositions:

3 + 509939 = 509942
31 + 509911 = 509942
79 + 509863 = 509942
109 + 509833 = 509942
211 + 509731 = 509942
283 + 509659 = 509942
373 + 509569 = 509942
379 + 509563 = 509942

Showing the first eight; more decompositions exist.
