Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500838, here are decompositions:

7 + 500831 = 500838
29 + 500809 = 500838
31 + 500807 = 500838
47 + 500791 = 500838
61 + 500777 = 500838
97 + 500741 = 500838
109 + 500729 = 500838
139 + 500699 = 500838

Showing the first eight; more decompositions exist.
