Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494920, here are decompositions:

3 + 494917 = 494920
17 + 494903 = 494920
47 + 494873 = 494920
71 + 494849 = 494920
131 + 494789 = 494920
137 + 494783 = 494920
197 + 494723 = 494920
227 + 494693 = 494920

Showing the first eight; more decompositions exist.
