Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502858, here are decompositions:

11 + 502847 = 502858
17 + 502841 = 502858
29 + 502829 = 502858
71 + 502787 = 502858
89 + 502769 = 502858
227 + 502631 = 502858
359 + 502499 = 502858
449 + 502409 = 502858

Showing the first eight; more decompositions exist.
