Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711918, here are decompositions:

31 + 8711887 = 8711918
67 + 8711851 = 8711918
97 + 8711821 = 8711918
151 + 8711767 = 8711918
181 + 8711737 = 8711918
199 + 8711719 = 8711918
211 + 8711707 = 8711918
349 + 8711569 = 8711918

Showing the first eight; more decompositions exist.
