Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494404, here are decompositions:

17 + 494387 = 494404
23 + 494381 = 494404
137 + 494267 = 494404
167 + 494237 = 494404
191 + 494213 = 494404
257 + 494147 = 494404
263 + 494141 = 494404
311 + 494093 = 494404

Showing the first eight; more decompositions exist.
