Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493406, here are decompositions:

3 + 493403 = 493406
7 + 493399 = 493406
13 + 493393 = 493406
37 + 493369 = 493406
73 + 493333 = 493406
127 + 493279 = 493406
157 + 493249 = 493406
163 + 493243 = 493406

Showing the first eight; more decompositions exist.
