Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501928, here are decompositions:

17 + 501911 = 501928
101 + 501827 = 501928
107 + 501821 = 501928
149 + 501779 = 501928
197 + 501731 = 501928
227 + 501701 = 501928
269 + 501659 = 501928
311 + 501617 = 501928

Showing the first eight; more decompositions exist.
