Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493228, here are decompositions:

11 + 493217 = 493228
17 + 493211 = 493228
59 + 493169 = 493228
89 + 493139 = 493228
101 + 493127 = 493228
107 + 493121 = 493228
179 + 493049 = 493228
227 + 493001 = 493228

Showing the first eight; more decompositions exist.
