Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494436, here are decompositions:

23 + 494413 = 494436
29 + 494407 = 494436
53 + 494383 = 494436
67 + 494369 = 494436
83 + 494353 = 494436
109 + 494327 = 494436
149 + 494287 = 494436
167 + 494269 = 494436

Showing the first eight; more decompositions exist.
