Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494820, here are decompositions:

17 + 494803 = 494820
31 + 494789 = 494820
37 + 494783 = 494820
59 + 494761 = 494820
61 + 494759 = 494820
71 + 494749 = 494820
83 + 494737 = 494820
89 + 494731 = 494820

Showing the first eight; more decompositions exist.
