Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501828, here are decompositions:

7 + 501821 = 501828
11 + 501817 = 501828
59 + 501769 = 501828
97 + 501731 = 501828
109 + 501719 = 501828
127 + 501701 = 501828
137 + 501691 = 501828
191 + 501637 = 501828

Showing the first eight; more decompositions exist.
