Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493686, here are decompositions:

29 + 493657 = 493686
43 + 493643 = 493686
59 + 493627 = 493686
79 + 493607 = 493686
103 + 493583 = 493686
107 + 493579 = 493686
113 + 493573 = 493686
163 + 493523 = 493686

Showing the first eight; more decompositions exist.
