Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501858, here are decompositions:

17 + 501841 = 501858
29 + 501829 = 501858
31 + 501827 = 501858
37 + 501821 = 501858
41 + 501817 = 501858
79 + 501779 = 501858
89 + 501769 = 501858
127 + 501731 = 501858

Showing the first eight; more decompositions exist.
