Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649494, here are decompositions:

3 + 8649491 = 8649494
31 + 8649463 = 8649494
43 + 8649451 = 8649494
103 + 8649391 = 8649494
127 + 8649367 = 8649494
151 + 8649343 = 8649494
163 + 8649331 = 8649494
211 + 8649283 = 8649494

Showing the first eight; more decompositions exist.
