Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649328, here are decompositions:

5 + 8649323 = 8649328
11 + 8649317 = 8649328
29 + 8649299 = 8649328
89 + 8649239 = 8649328
101 + 8649227 = 8649328
131 + 8649197 = 8649328
137 + 8649191 = 8649328
257 + 8649071 = 8649328

Showing the first eight; more decompositions exist.
