Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494790, here are decompositions:

7 + 494783 = 494790
29 + 494761 = 494790
31 + 494759 = 494790
41 + 494749 = 494790
47 + 494743 = 494790
53 + 494737 = 494790
59 + 494731 = 494790
67 + 494723 = 494790

Showing the first eight; more decompositions exist.
