Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493018, here are decompositions:

5 + 493013 = 493018
17 + 493001 = 493018
107 + 492911 = 493018
179 + 492839 = 493018
257 + 492761 = 493018
311 + 492707 = 493018
347 + 492671 = 493018
359 + 492659 = 493018

Showing the first eight; more decompositions exist.
