Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494940, here are decompositions:

7 + 494933 = 494940
13 + 494927 = 494940
23 + 494917 = 494940
37 + 494903 = 494940
41 + 494899 = 494940
67 + 494873 = 494940
97 + 494843 = 494940
137 + 494803 = 494940

Showing the first eight; more decompositions exist.
