Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497730, here are decompositions:

11 + 497719 = 497730
19 + 497711 = 497730
29 + 497701 = 497730
41 + 497689 = 497730
53 + 497677 = 497730
59 + 497671 = 497730
67 + 497663 = 497730
71 + 497659 = 497730

Showing the first eight; more decompositions exist.
