Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635666, here are decompositions:

3 + 8635663 = 8635666
29 + 8635637 = 8635666
59 + 8635607 = 8635666
107 + 8635559 = 8635666
113 + 8635553 = 8635666
197 + 8635469 = 8635666
233 + 8635433 = 8635666
257 + 8635409 = 8635666

Showing the first eight; more decompositions exist.
