Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665662, here are decompositions:

11 + 8665651 = 8665662
13 + 8665649 = 8665662
29 + 8665633 = 8665662
43 + 8665619 = 8665662
59 + 8665603 = 8665662
79 + 8665583 = 8665662
101 + 8665561 = 8665662
163 + 8665499 = 8665662

Showing the first eight; more decompositions exist.
