Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494638, here are decompositions:

17 + 494621 = 494638
29 + 494609 = 494638
47 + 494591 = 494638
71 + 494567 = 494638
167 + 494471 = 494638
197 + 494441 = 494638
251 + 494387 = 494638
257 + 494381 = 494638

Showing the first eight; more decompositions exist.
