Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494494, here are decompositions:

23 + 494471 = 494494
53 + 494441 = 494494
107 + 494387 = 494494
113 + 494381 = 494494
167 + 494327 = 494494
227 + 494267 = 494494
257 + 494237 = 494494
281 + 494213 = 494494

Showing the first eight; more decompositions exist.
