Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494992, here are decompositions:

5 + 494987 = 494992
53 + 494939 = 494992
59 + 494933 = 494992
89 + 494903 = 494992
149 + 494843 = 494992
233 + 494759 = 494992
269 + 494723 = 494992
293 + 494699 = 494992

Showing the first eight; more decompositions exist.
