Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8864, here are decompositions:

3 + 8861 = 8864
43 + 8821 = 8864
61 + 8803 = 8864
103 + 8761 = 8864
127 + 8737 = 8864
151 + 8713 = 8864
157 + 8707 = 8864
223 + 8641 = 8864

Showing the first eight; more decompositions exist.
