Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8918, here are decompositions:

31 + 8887 = 8918
79 + 8839 = 8918
97 + 8821 = 8918
139 + 8779 = 8918
157 + 8761 = 8918
181 + 8737 = 8918
199 + 8719 = 8918
211 + 8707 = 8918

Showing the first eight; more decompositions exist.
