Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664728, here are decompositions:

67 + 8664661 = 8664728
181 + 8664547 = 8664728
199 + 8664529 = 8664728
211 + 8664517 = 8664728
277 + 8664451 = 8664728
307 + 8664421 = 8664728
547 + 8664181 = 8664728
571 + 8664157 = 8664728

Showing the first eight; more decompositions exist.
