Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497578, here are decompositions:

17 + 497561 = 497578
41 + 497537 = 497578
71 + 497507 = 497578
167 + 497411 = 497578
227 + 497351 = 497578
239 + 497339 = 497578
269 + 497309 = 497578
281 + 497297 = 497578

Showing the first eight; more decompositions exist.
