Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500868, here are decompositions:

7 + 500861 = 500868
29 + 500839 = 500868
37 + 500831 = 500868
59 + 500809 = 500868
61 + 500807 = 500868
127 + 500741 = 500868
139 + 500729 = 500868
149 + 500719 = 500868

Showing the first eight; more decompositions exist.
