Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649324, here are decompositions:

7 + 8649317 = 8649324
31 + 8649293 = 8649324
41 + 8649283 = 8649324
71 + 8649253 = 8649324
83 + 8649241 = 8649324
97 + 8649227 = 8649324
113 + 8649211 = 8649324
127 + 8649197 = 8649324

Showing the first eight; more decompositions exist.
