Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493566, here are decompositions:

43 + 493523 = 493566
103 + 493463 = 493566
109 + 493457 = 493566
163 + 493403 = 493566
167 + 493399 = 493566
173 + 493393 = 493566
197 + 493369 = 493566
233 + 493333 = 493566

Showing the first eight; more decompositions exist.
