Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492918, here are decompositions:

7 + 492911 = 492918
17 + 492901 = 492918
47 + 492871 = 492918
79 + 492839 = 492918
137 + 492781 = 492918
149 + 492769 = 492918
157 + 492761 = 492918
197 + 492721 = 492918

Showing the first eight; more decompositions exist.
