Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629666, here are decompositions:

5 + 8629661 = 8629666
29 + 8629637 = 8629666
53 + 8629613 = 8629666
83 + 8629583 = 8629666
233 + 8629433 = 8629666
257 + 8629409 = 8629666
317 + 8629349 = 8629666
467 + 8629199 = 8629666

Showing the first eight; more decompositions exist.
