Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502818, here are decompositions:

11 + 502807 = 502818
31 + 502787 = 502818
37 + 502781 = 502818
47 + 502771 = 502818
89 + 502729 = 502818
101 + 502717 = 502818
131 + 502687 = 502818
149 + 502669 = 502818

Showing the first eight; more decompositions exist.
