Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669660, here are decompositions:

3 + 8669657 = 8669660
31 + 8669629 = 8669660
37 + 8669623 = 8669660
67 + 8669593 = 8669660
271 + 8669389 = 8669660
331 + 8669329 = 8669660
367 + 8669293 = 8669660
409 + 8669251 = 8669660

Showing the first eight; more decompositions exist.
