Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493450, here are decompositions:

3 + 493447 = 493450
17 + 493433 = 493450
47 + 493403 = 493450
53 + 493397 = 493450
137 + 493313 = 493450
149 + 493301 = 493450
173 + 493277 = 493450
233 + 493217 = 493450

Showing the first eight; more decompositions exist.
