Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497690, here are decompositions:

13 + 497677 = 497690
19 + 497671 = 497690
31 + 497659 = 497690
103 + 497587 = 497690
139 + 497551 = 497690
181 + 497509 = 497690
199 + 497491 = 497690
211 + 497479 = 497690

Showing the first eight; more decompositions exist.
