Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499638, here are decompositions:

5 + 499633 = 499638
17 + 499621 = 499638
31 + 499607 = 499638
37 + 499601 = 499638
47 + 499591 = 499638
67 + 499571 = 499638
79 + 499559 = 499638
89 + 499549 = 499638

Showing the first eight; more decompositions exist.
