Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649340, here are decompositions:

17 + 8649323 = 8649340
23 + 8649317 = 8649340
41 + 8649299 = 8649340
47 + 8649293 = 8649340
101 + 8649239 = 8649340
113 + 8649227 = 8649340
149 + 8649191 = 8649340
269 + 8649071 = 8649340

Showing the first eight; more decompositions exist.
