Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494392, here are decompositions:

5 + 494387 = 494392
11 + 494381 = 494392
23 + 494369 = 494392
179 + 494213 = 494392
251 + 494141 = 494392
263 + 494129 = 494392
419 + 493973 = 494392
461 + 493931 = 494392

Showing the first eight; more decompositions exist.
