Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497538, here are decompositions:

17 + 497521 = 497538
29 + 497509 = 497538
31 + 497507 = 497538
37 + 497501 = 497538
47 + 497491 = 497538
59 + 497479 = 497538
89 + 497449 = 497538
127 + 497411 = 497538

Showing the first eight; more decompositions exist.
