Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611666, here are decompositions:

3 + 8611663 = 8611666
23 + 8611643 = 8611666
47 + 8611619 = 8611666
53 + 8611613 = 8611666
137 + 8611529 = 8611666
179 + 8611487 = 8611666
227 + 8611439 = 8611666
233 + 8611433 = 8611666

Showing the first eight; more decompositions exist.
