Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611566, here are decompositions:

17 + 8611549 = 8611566
37 + 8611529 = 8611566
43 + 8611523 = 8611566
79 + 8611487 = 8611566
127 + 8611439 = 8611566
163 + 8611403 = 8611566
167 + 8611399 = 8611566
263 + 8611303 = 8611566

Showing the first eight; more decompositions exist.
