Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649464, here are decompositions:

13 + 8649451 = 8649464
73 + 8649391 = 8649464
97 + 8649367 = 8649464
181 + 8649283 = 8649464
211 + 8649253 = 8649464
223 + 8649241 = 8649464
277 + 8649187 = 8649464
463 + 8649001 = 8649464

Showing the first eight; more decompositions exist.
