Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497680, here are decompositions:

3 + 497677 = 497680
17 + 497663 = 497680
47 + 497633 = 497680
83 + 497597 = 497680
101 + 497579 = 497680
173 + 497507 = 497680
179 + 497501 = 497680
257 + 497423 = 497680

Showing the first eight; more decompositions exist.
