Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711180, here are decompositions:

19 + 8711161 = 8711180
43 + 8711137 = 8711180
97 + 8711083 = 8711180
109 + 8711071 = 8711180
223 + 8710957 = 8711180
241 + 8710939 = 8711180
271 + 8710909 = 8711180
277 + 8710903 = 8711180

Showing the first eight; more decompositions exist.
