Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493986, here are decompositions:

7 + 493979 = 493986
13 + 493973 = 493986
19 + 493967 = 493986
47 + 493939 = 493986
67 + 493919 = 493986
89 + 493897 = 493986
109 + 493877 = 493986
113 + 493873 = 493986

Showing the first eight; more decompositions exist.
