Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494644, here are decompositions:

5 + 494639 = 494644
23 + 494621 = 494644
53 + 494591 = 494644
83 + 494561 = 494644
173 + 494471 = 494644
257 + 494387 = 494644
263 + 494381 = 494644
317 + 494327 = 494644

Showing the first eight; more decompositions exist.
