Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494788, here are decompositions:

5 + 494783 = 494788
29 + 494759 = 494788
89 + 494699 = 494788
101 + 494687 = 494788
137 + 494651 = 494788
149 + 494639 = 494788
167 + 494621 = 494788
179 + 494609 = 494788

Showing the first eight; more decompositions exist.
