Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494458, here are decompositions:

17 + 494441 = 494458
71 + 494387 = 494458
89 + 494369 = 494458
131 + 494327 = 494458
191 + 494267 = 494458
311 + 494147 = 494458
317 + 494141 = 494458
389 + 494069 = 494458

Showing the first eight; more decompositions exist.
