Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494408, here are decompositions:

67 + 494341 = 494408
127 + 494281 = 494408
139 + 494269 = 494408
151 + 494257 = 494408
157 + 494251 = 494408
241 + 494167 = 494408
307 + 494101 = 494408
331 + 494077 = 494408

Showing the first eight; more decompositions exist.
