Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497790, here are decompositions:

17 + 497773 = 497790
19 + 497771 = 497790
53 + 497737 = 497790
61 + 497729 = 497790
71 + 497719 = 497790
79 + 497711 = 497790
89 + 497701 = 497790
101 + 497689 = 497790

Showing the first eight; more decompositions exist.
