Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493442, here are decompositions:

43 + 493399 = 493442
73 + 493369 = 493442
109 + 493333 = 493442
151 + 493291 = 493442
163 + 493279 = 493442
193 + 493249 = 493442
199 + 493243 = 493442
211 + 493231 = 493442

Showing the first eight; more decompositions exist.
