Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497644, here are decompositions:

11 + 497633 = 497644
41 + 497603 = 497644
47 + 497597 = 497644
83 + 497561 = 497644
107 + 497537 = 497644
137 + 497507 = 497644
227 + 497417 = 497644
233 + 497411 = 497644

Showing the first eight; more decompositions exist.
