Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497686, here are decompositions:

23 + 497663 = 497686
53 + 497633 = 497686
83 + 497603 = 497686
89 + 497597 = 497686
107 + 497579 = 497686
149 + 497537 = 497686
179 + 497507 = 497686
263 + 497423 = 497686

Showing the first eight; more decompositions exist.
