Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649408, here are decompositions:

17 + 8649391 = 8649408
37 + 8649371 = 8649408
41 + 8649367 = 8649408
59 + 8649349 = 8649408
109 + 8649299 = 8649408
167 + 8649241 = 8649408
181 + 8649227 = 8649408
197 + 8649211 = 8649408

Showing the first eight; more decompositions exist.
