Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666416, here are decompositions:

23 + 8666393 = 8666416
29 + 8666387 = 8666416
47 + 8666369 = 8666416
89 + 8666327 = 8666416
179 + 8666237 = 8666416
197 + 8666219 = 8666416
233 + 8666183 = 8666416
257 + 8666159 = 8666416

Showing the first eight; more decompositions exist.
