Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494800, here are decompositions:

11 + 494789 = 494800
17 + 494783 = 494800
41 + 494759 = 494800
101 + 494699 = 494800
107 + 494693 = 494800
113 + 494687 = 494800
149 + 494651 = 494800
179 + 494621 = 494800

Showing the first eight; more decompositions exist.
