Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497816, here are decompositions:

3 + 497813 = 497816
43 + 497773 = 497816
79 + 497737 = 497816
97 + 497719 = 497816
127 + 497689 = 497816
139 + 497677 = 497816
157 + 497659 = 497816
229 + 497587 = 497816

Showing the first eight; more decompositions exist.
