Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497782, here are decompositions:

11 + 497771 = 497782
41 + 497741 = 497782
53 + 497729 = 497782
71 + 497711 = 497782
149 + 497633 = 497782
179 + 497603 = 497782
281 + 497501 = 497782
359 + 497423 = 497782

Showing the first eight; more decompositions exist.
