Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494406, here are decompositions:

19 + 494387 = 494406
23 + 494383 = 494406
37 + 494369 = 494406
47 + 494359 = 494406
53 + 494353 = 494406
79 + 494327 = 494406
89 + 494317 = 494406
137 + 494269 = 494406

Showing the first eight; more decompositions exist.
