Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509908, here are decompositions:

29 + 509879 = 509908
41 + 509867 = 509908
71 + 509837 = 509908
107 + 509801 = 509908
167 + 509741 = 509908
227 + 509681 = 509908
317 + 509591 = 509908
359 + 509549 = 509908

Showing the first eight; more decompositions exist.
