Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492666, here are decompositions:

7 + 492659 = 492666
19 + 492647 = 492666
37 + 492629 = 492666
47 + 492619 = 492666
79 + 492587 = 492666
103 + 492563 = 492666
179 + 492487 = 492666
199 + 492467 = 492666

Showing the first eight; more decompositions exist.
