Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501906, here are decompositions:

17 + 501889 = 501906
43 + 501863 = 501906
79 + 501827 = 501906
89 + 501817 = 501906
103 + 501803 = 501906
127 + 501779 = 501906
137 + 501769 = 501906
199 + 501707 = 501906

Showing the first eight; more decompositions exist.
