Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649608, here are decompositions:

139 + 8649469 = 8649608
157 + 8649451 = 8649608
199 + 8649409 = 8649608
241 + 8649367 = 8649608
277 + 8649331 = 8649608
367 + 8649241 = 8649608
397 + 8649211 = 8649608
421 + 8649187 = 8649608

Showing the first eight; more decompositions exist.
