Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501868, here are decompositions:

5 + 501863 = 501868
41 + 501827 = 501868
47 + 501821 = 501868
89 + 501779 = 501868
137 + 501731 = 501868
149 + 501719 = 501868
167 + 501701 = 501868
251 + 501617 = 501868

Showing the first eight; more decompositions exist.
