Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493458, here are decompositions:

11 + 493447 = 493458
59 + 493399 = 493458
61 + 493397 = 493458
89 + 493369 = 493458
107 + 493351 = 493458
157 + 493301 = 493458
167 + 493291 = 493458
179 + 493279 = 493458

Showing the first eight; more decompositions exist.
