Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501786, here are decompositions:

7 + 501779 = 501786
17 + 501769 = 501786
67 + 501719 = 501786
79 + 501707 = 501786
83 + 501703 = 501786
127 + 501659 = 501786
149 + 501637 = 501786
163 + 501623 = 501786

Showing the first eight; more decompositions exist.
