Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666466, here are decompositions:

7 + 8666459 = 8666466
23 + 8666443 = 8666466
47 + 8666419 = 8666466
73 + 8666393 = 8666466
79 + 8666387 = 8666466
97 + 8666369 = 8666466
139 + 8666327 = 8666466
197 + 8666269 = 8666466

Showing the first eight; more decompositions exist.
