Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649410, here are decompositions:

19 + 8649391 = 8649410
43 + 8649367 = 8649410
61 + 8649349 = 8649410
67 + 8649343 = 8649410
79 + 8649331 = 8649410
127 + 8649283 = 8649410
157 + 8649253 = 8649410
199 + 8649211 = 8649410

Showing the first eight; more decompositions exist.
