Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666446, here are decompositions:

3 + 8666443 = 8666446
29 + 8666417 = 8666446
53 + 8666393 = 8666446
59 + 8666387 = 8666446
227 + 8666219 = 8666446
263 + 8666183 = 8666446
293 + 8666153 = 8666446
353 + 8666093 = 8666446

Showing the first eight; more decompositions exist.
