Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649698, here are decompositions:

7 + 8649691 = 8649698
37 + 8649661 = 8649698
61 + 8649637 = 8649698
181 + 8649517 = 8649698
229 + 8649469 = 8649698
307 + 8649391 = 8649698
331 + 8649367 = 8649698
349 + 8649349 = 8649698

Showing the first eight; more decompositions exist.
