Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666472, here are decompositions:

13 + 8666459 = 8666472
29 + 8666443 = 8666472
41 + 8666431 = 8666472
53 + 8666419 = 8666472
79 + 8666393 = 8666472
103 + 8666369 = 8666472
149 + 8666323 = 8666472
181 + 8666291 = 8666472

Showing the first eight; more decompositions exist.
