Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494440, here are decompositions:

53 + 494387 = 494440
59 + 494381 = 494440
71 + 494369 = 494440
113 + 494327 = 494440
173 + 494267 = 494440
227 + 494213 = 494440
293 + 494147 = 494440
311 + 494129 = 494440

Showing the first eight; more decompositions exist.
