Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711864, here are decompositions:

13 + 8711851 = 8711864
43 + 8711821 = 8711864
67 + 8711797 = 8711864
97 + 8711767 = 8711864
127 + 8711737 = 8711864
157 + 8711707 = 8711864
181 + 8711683 = 8711864
211 + 8711653 = 8711864

Showing the first eight; more decompositions exist.
