Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493186, here are decompositions:

17 + 493169 = 493186
47 + 493139 = 493186
53 + 493133 = 493186
59 + 493127 = 493186
137 + 493049 = 493186
173 + 493013 = 493186
293 + 492893 = 493186
347 + 492839 = 493186

Showing the first eight; more decompositions exist.
