Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493290, here are decompositions:

11 + 493279 = 493290
13 + 493277 = 493290
41 + 493249 = 493290
47 + 493243 = 493290
59 + 493231 = 493290
71 + 493219 = 493290
73 + 493217 = 493290
79 + 493211 = 493290

Showing the first eight; more decompositions exist.
