Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497638, here are decompositions:

5 + 497633 = 497638
41 + 497597 = 497638
59 + 497579 = 497638
101 + 497537 = 497638
131 + 497507 = 497638
137 + 497501 = 497638
227 + 497411 = 497638
347 + 497291 = 497638

Showing the first eight; more decompositions exist.
