Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497900, here are decompositions:

31 + 497869 = 497900
61 + 497839 = 497900
127 + 497773 = 497900
163 + 497737 = 497900
181 + 497719 = 497900
199 + 497701 = 497900
211 + 497689 = 497900
223 + 497677 = 497900

Showing the first eight; more decompositions exist.
