Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493660, here are decompositions:

3 + 493657 = 493660
17 + 493643 = 493660
53 + 493607 = 493660
137 + 493523 = 493660
179 + 493481 = 493660
197 + 493463 = 493660
227 + 493433 = 493660
257 + 493403 = 493660

Showing the first eight; more decompositions exist.
