Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493190, here are decompositions:

13 + 493177 = 493190
31 + 493159 = 493190
43 + 493147 = 493190
67 + 493123 = 493190
79 + 493111 = 493190
97 + 493093 = 493190
163 + 493027 = 493190
211 + 492979 = 493190

Showing the first eight; more decompositions exist.
