Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667566, here are decompositions:

3 + 8667563 = 8667566
7 + 8667559 = 8667566
109 + 8667457 = 8667566
139 + 8667427 = 8667566
163 + 8667403 = 8667566
277 + 8667289 = 8667566
463 + 8667103 = 8667566
487 + 8667079 = 8667566

Showing the first eight; more decompositions exist.
