Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509830, here are decompositions:

29 + 509801 = 509830
47 + 509783 = 509830
89 + 509741 = 509830
107 + 509723 = 509830
131 + 509699 = 509830
137 + 509693 = 509830
149 + 509681 = 509830
197 + 509633 = 509830

Showing the first eight; more decompositions exist.
