Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711240, here are decompositions:

3 + 8711237 = 8711240
61 + 8711179 = 8711240
79 + 8711161 = 8711240
103 + 8711137 = 8711240
157 + 8711083 = 8711240
229 + 8711011 = 8711240
277 + 8710963 = 8711240
283 + 8710957 = 8711240

Showing the first eight; more decompositions exist.
