Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715280, here are decompositions:

11 + 8715269 = 8715280
17 + 8715263 = 8715280
47 + 8715233 = 8715280
71 + 8715209 = 8715280
89 + 8715191 = 8715280
137 + 8715143 = 8715280
173 + 8715107 = 8715280
239 + 8715041 = 8715280

Showing the first eight; more decompositions exist.
