Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982666, here are decompositions:

23 + 982643 = 982666
53 + 982613 = 982666
89 + 982577 = 982666
107 + 982559 = 982666
173 + 982493 = 982666
263 + 982403 = 982666
449 + 982217 = 982666
479 + 982187 = 982666

Showing the first eight; more decompositions exist.
