Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493636, here are decompositions:

29 + 493607 = 493636
53 + 493583 = 493636
113 + 493523 = 493636
173 + 493463 = 493636
179 + 493457 = 493636
233 + 493403 = 493636
239 + 493397 = 493636
359 + 493277 = 493636

Showing the first eight; more decompositions exist.
