Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499228, here are decompositions:

17 + 499211 = 499228
47 + 499181 = 499228
71 + 499157 = 499228
89 + 499139 = 499228
101 + 499127 = 499228
239 + 498989 = 499228
251 + 498977 = 499228
281 + 498947 = 499228

Showing the first eight; more decompositions exist.
