Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509916, here are decompositions:

5 + 509911 = 509916
7 + 509909 = 509916
37 + 509879 = 509916
53 + 509863 = 509916
73 + 509843 = 509916
79 + 509837 = 509916
83 + 509833 = 509916
149 + 509767 = 509916

Showing the first eight; more decompositions exist.
