Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501850, here are decompositions:

23 + 501827 = 501850
29 + 501821 = 501850
47 + 501803 = 501850
71 + 501779 = 501850
131 + 501719 = 501850
149 + 501701 = 501850
191 + 501659 = 501850
227 + 501623 = 501850

Showing the first eight; more decompositions exist.
