Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493386, here are decompositions:

17 + 493369 = 493386
53 + 493333 = 493386
73 + 493313 = 493386
107 + 493279 = 493386
109 + 493277 = 493386
137 + 493249 = 493386
167 + 493219 = 493386
193 + 493193 = 493386

Showing the first eight; more decompositions exist.
