Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499212, here are decompositions:

23 + 499189 = 499212
29 + 499183 = 499212
31 + 499181 = 499212
53 + 499159 = 499212
61 + 499151 = 499212
71 + 499141 = 499212
73 + 499139 = 499212
79 + 499133 = 499212

Showing the first eight; more decompositions exist.
