Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493480, here are decompositions:

17 + 493463 = 493480
23 + 493457 = 493480
47 + 493433 = 493480
83 + 493397 = 493480
167 + 493313 = 493480
179 + 493301 = 493480
263 + 493217 = 493480
269 + 493211 = 493480

Showing the first eight; more decompositions exist.
