Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493638, here are decompositions:

11 + 493627 = 493638
17 + 493621 = 493638
31 + 493607 = 493638
59 + 493579 = 493638
71 + 493567 = 493638
97 + 493541 = 493638
107 + 493531 = 493638
157 + 493481 = 493638

Showing the first eight; more decompositions exist.
