Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509854, here are decompositions:

11 + 509843 = 509854
17 + 509837 = 509854
53 + 509801 = 509854
71 + 509783 = 509854
113 + 509741 = 509854
131 + 509723 = 509854
167 + 509687 = 509854
173 + 509681 = 509854

Showing the first eight; more decompositions exist.
