Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8816, here are decompositions:

13 + 8803 = 8816
37 + 8779 = 8816
79 + 8737 = 8816
97 + 8719 = 8816
103 + 8713 = 8816
109 + 8707 = 8816
127 + 8689 = 8816
139 + 8677 = 8816

Showing the first eight; more decompositions exist.
