Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500826, here are decompositions:

17 + 500809 = 500826
19 + 500807 = 500826
97 + 500729 = 500826
103 + 500723 = 500826
107 + 500719 = 500826
113 + 500713 = 500826
127 + 500699 = 500826
149 + 500677 = 500826

Showing the first eight; more decompositions exist.
