Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646280, here are decompositions:

3 + 8646277 = 8646280
11 + 8646269 = 8646280
23 + 8646257 = 8646280
47 + 8646233 = 8646280
53 + 8646227 = 8646280
59 + 8646221 = 8646280
173 + 8646107 = 8646280
263 + 8646017 = 8646280

Showing the first eight; more decompositions exist.
