Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493666, here are decompositions:

23 + 493643 = 493666
59 + 493607 = 493666
83 + 493583 = 493666
233 + 493433 = 493666
263 + 493403 = 493666
269 + 493397 = 493666
353 + 493313 = 493666
389 + 493277 = 493666

Showing the first eight; more decompositions exist.
