Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497778, here are decompositions:

5 + 497773 = 497778
7 + 497771 = 497778
37 + 497741 = 497778
41 + 497737 = 497778
59 + 497719 = 497778
67 + 497711 = 497778
89 + 497689 = 497778
101 + 497677 = 497778

Showing the first eight; more decompositions exist.
