Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497540, here are decompositions:

3 + 497537 = 497540
19 + 497521 = 497540
31 + 497509 = 497540
61 + 497479 = 497540
67 + 497473 = 497540
79 + 497461 = 497540
151 + 497389 = 497540
271 + 497269 = 497540

Showing the first eight; more decompositions exist.
