Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649398, here are decompositions:

7 + 8649391 = 8649398
31 + 8649367 = 8649398
67 + 8649331 = 8649398
157 + 8649241 = 8649398
211 + 8649187 = 8649398
337 + 8649061 = 8649398
349 + 8649049 = 8649398
397 + 8649001 = 8649398

Showing the first eight; more decompositions exist.
