Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509874, here are decompositions:

7 + 509867 = 509874
11 + 509863 = 509874
31 + 509843 = 509874
37 + 509837 = 509874
41 + 509833 = 509874
73 + 509801 = 509874
107 + 509767 = 509874
137 + 509737 = 509874

Showing the first eight; more decompositions exist.
