Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509906, here are decompositions:

43 + 509863 = 509906
73 + 509833 = 509906
109 + 509797 = 509906
139 + 509767 = 509906
283 + 509623 = 509906
337 + 509569 = 509906
349 + 509557 = 509906
457 + 509449 = 509906

Showing the first eight; more decompositions exist.
