Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666476, here are decompositions:

17 + 8666459 = 8666476
59 + 8666417 = 8666476
83 + 8666393 = 8666476
89 + 8666387 = 8666476
107 + 8666369 = 8666476
149 + 8666327 = 8666476
239 + 8666237 = 8666476
257 + 8666219 = 8666476

Showing the first eight; more decompositions exist.
