Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666456, here are decompositions:

13 + 8666443 = 8666456
37 + 8666419 = 8666456
109 + 8666347 = 8666456
283 + 8666173 = 8666456
397 + 8666059 = 8666456
433 + 8666023 = 8666456
439 + 8666017 = 8666456
457 + 8665999 = 8666456

Showing the first eight; more decompositions exist.
