Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8652280, here are decompositions:

17 + 8652263 = 8652280
23 + 8652257 = 8652280
53 + 8652227 = 8652280
137 + 8652143 = 8652280
179 + 8652101 = 8652280
227 + 8652053 = 8652280
233 + 8652047 = 8652280
239 + 8652041 = 8652280

Showing the first eight; more decompositions exist.
