Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493454, here are decompositions:

7 + 493447 = 493454
61 + 493393 = 493454
103 + 493351 = 493454
163 + 493291 = 493454
211 + 493243 = 493454
223 + 493231 = 493454
277 + 493177 = 493454
307 + 493147 = 493454

Showing the first eight; more decompositions exist.
