Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711976, here are decompositions:

5 + 8711971 = 8711976
23 + 8711953 = 8711976
43 + 8711933 = 8711976
79 + 8711897 = 8711976
89 + 8711887 = 8711976
107 + 8711869 = 8711976
109 + 8711867 = 8711976
113 + 8711863 = 8711976

Showing the first eight; more decompositions exist.
