Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493456, here are decompositions:

23 + 493433 = 493456
53 + 493403 = 493456
59 + 493397 = 493456
179 + 493277 = 493456
239 + 493217 = 493456
263 + 493193 = 493456
317 + 493139 = 493456
347 + 493109 = 493456

Showing the first eight; more decompositions exist.
