Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499218, here are decompositions:

7 + 499211 = 499218
29 + 499189 = 499218
37 + 499181 = 499218
59 + 499159 = 499218
61 + 499157 = 499218
67 + 499151 = 499218
79 + 499139 = 499218
89 + 499129 = 499218

Showing the first eight; more decompositions exist.
