Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499230, here are decompositions:

19 + 499211 = 499230
41 + 499189 = 499230
47 + 499183 = 499230
71 + 499159 = 499230
73 + 499157 = 499230
79 + 499151 = 499230
89 + 499141 = 499230
97 + 499133 = 499230

Showing the first eight; more decompositions exist.
