Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497870, here are decompositions:

3 + 497867 = 497870
19 + 497851 = 497870
31 + 497839 = 497870
97 + 497773 = 497870
151 + 497719 = 497870
181 + 497689 = 497870
193 + 497677 = 497870
199 + 497671 = 497870

Showing the first eight; more decompositions exist.
