Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736280, here are decompositions:

17 + 8736263 = 8736280
71 + 8736209 = 8736280
89 + 8736191 = 8736280
101 + 8736179 = 8736280
107 + 8736173 = 8736280
191 + 8736089 = 8736280
239 + 8736041 = 8736280
347 + 8735933 = 8736280

Showing the first eight; more decompositions exist.
