Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494866, here are decompositions:

17 + 494849 = 494866
23 + 494843 = 494866
83 + 494783 = 494866
107 + 494759 = 494866
167 + 494699 = 494866
173 + 494693 = 494866
179 + 494687 = 494866
227 + 494639 = 494866

Showing the first eight; more decompositions exist.
