Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518862, here are decompositions:

31 + 518831 = 518862
53 + 518809 = 518862
59 + 518803 = 518862
61 + 518801 = 518862
83 + 518779 = 518862
101 + 518761 = 518862
103 + 518759 = 518862
163 + 518699 = 518862

Showing the first eight; more decompositions exist.
