Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499818, here are decompositions:

17 + 499801 = 499818
31 + 499787 = 499818
37 + 499781 = 499818
71 + 499747 = 499818
79 + 499739 = 499818
89 + 499729 = 499818
101 + 499717 = 499818
107 + 499711 = 499818

Showing the first eight; more decompositions exist.
