Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493288, here are decompositions:

11 + 493277 = 493288
71 + 493217 = 493288
149 + 493139 = 493288
167 + 493121 = 493288
179 + 493109 = 493288
239 + 493049 = 493288
449 + 492839 = 493288
557 + 492731 = 493288

Showing the first eight; more decompositions exist.
