Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509938, here are decompositions:

17 + 509921 = 509938
29 + 509909 = 509938
59 + 509879 = 509938
71 + 509867 = 509938
101 + 509837 = 509938
137 + 509801 = 509938
197 + 509741 = 509938
239 + 509699 = 509938

Showing the first eight; more decompositions exist.
