Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493490, here are decompositions:

43 + 493447 = 493490
97 + 493393 = 493490
139 + 493351 = 493490
157 + 493333 = 493490
199 + 493291 = 493490
211 + 493279 = 493490
241 + 493249 = 493490
271 + 493219 = 493490

Showing the first eight; more decompositions exist.
