Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492018, here are decompositions:

5 + 492013 = 492018
11 + 492007 = 492018
41 + 491977 = 492018
67 + 491951 = 492018
151 + 491867 = 492018
167 + 491851 = 492018
181 + 491837 = 492018
199 + 491819 = 492018

Showing the first eight; more decompositions exist.
