Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493486, here are decompositions:

5 + 493481 = 493486
23 + 493463 = 493486
29 + 493457 = 493486
53 + 493433 = 493486
83 + 493403 = 493486
89 + 493397 = 493486
173 + 493313 = 493486
269 + 493217 = 493486

Showing the first eight; more decompositions exist.
