Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501958, here are decompositions:

5 + 501953 = 501958
11 + 501947 = 501958
47 + 501911 = 501958
131 + 501827 = 501958
137 + 501821 = 501958
179 + 501779 = 501958
227 + 501731 = 501958
239 + 501719 = 501958

Showing the first eight; more decompositions exist.
