Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649434, here are decompositions:

43 + 8649391 = 8649434
67 + 8649367 = 8649434
103 + 8649331 = 8649434
151 + 8649283 = 8649434
181 + 8649253 = 8649434
193 + 8649241 = 8649434
223 + 8649211 = 8649434
331 + 8649103 = 8649434

Showing the first eight; more decompositions exist.
