Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499178, here are decompositions:

19 + 499159 = 499178
37 + 499141 = 499178
61 + 499117 = 499178
79 + 499099 = 499178
139 + 499039 = 499178
151 + 499027 = 499178
157 + 499021 = 499178
241 + 498937 = 499178

Showing the first eight; more decompositions exist.
