Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493188, here are decompositions:

11 + 493177 = 493188
19 + 493169 = 493188
29 + 493159 = 493188
41 + 493147 = 493188
61 + 493127 = 493188
67 + 493121 = 493188
79 + 493109 = 493188
139 + 493049 = 493188

Showing the first eight; more decompositions exist.
