Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606666, here are decompositions:

67 + 8606599 = 8606666
109 + 8606557 = 8606666
139 + 8606527 = 8606666
157 + 8606509 = 8606666
223 + 8606443 = 8606666
337 + 8606329 = 8606666
373 + 8606293 = 8606666
379 + 8606287 = 8606666

Showing the first eight; more decompositions exist.
