Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500878, here are decompositions:

5 + 500873 = 500878
17 + 500861 = 500878
47 + 500831 = 500878
71 + 500807 = 500878
101 + 500777 = 500878
137 + 500741 = 500878
149 + 500729 = 500878
179 + 500699 = 500878

Showing the first eight; more decompositions exist.
