Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497918, here are decompositions:

19 + 497899 = 497918
67 + 497851 = 497918
79 + 497839 = 497918
181 + 497737 = 497918
199 + 497719 = 497918
229 + 497689 = 497918
241 + 497677 = 497918
331 + 497587 = 497918

Showing the first eight; more decompositions exist.
