Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509958, here are decompositions:

11 + 509947 = 509958
19 + 509939 = 509958
37 + 509921 = 509958
47 + 509911 = 509958
79 + 509879 = 509958
157 + 509801 = 509958
191 + 509767 = 509958
227 + 509731 = 509958

Showing the first eight; more decompositions exist.
