Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649264, here are decompositions:

11 + 8649253 = 8649264
23 + 8649241 = 8649264
37 + 8649227 = 8649264
53 + 8649211 = 8649264
67 + 8649197 = 8649264
73 + 8649191 = 8649264
193 + 8649071 = 8649264
241 + 8649023 = 8649264

Showing the first eight; more decompositions exist.
