Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494986, here are decompositions:

47 + 494939 = 494986
53 + 494933 = 494986
59 + 494927 = 494986
83 + 494903 = 494986
113 + 494873 = 494986
137 + 494849 = 494986
197 + 494789 = 494986
227 + 494759 = 494986

Showing the first eight; more decompositions exist.
