Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499188, here are decompositions:

5 + 499183 = 499188
7 + 499181 = 499188
29 + 499159 = 499188
31 + 499157 = 499188
37 + 499151 = 499188
47 + 499141 = 499188
59 + 499129 = 499188
61 + 499127 = 499188

Showing the first eight; more decompositions exist.
