Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499668, here are decompositions:

5 + 499663 = 499668
7 + 499661 = 499668
19 + 499649 = 499668
31 + 499637 = 499668
47 + 499621 = 499668
61 + 499607 = 499668
67 + 499601 = 499668
97 + 499571 = 499668

Showing the first eight; more decompositions exist.
