Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497666, here are decompositions:

3 + 497663 = 497666
7 + 497659 = 497666
79 + 497587 = 497666
109 + 497557 = 497666
157 + 497509 = 497666
193 + 497473 = 497666
277 + 497389 = 497666
397 + 497269 = 497666

Showing the first eight; more decompositions exist.
