Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649530, here are decompositions:

13 + 8649517 = 8649530
61 + 8649469 = 8649530
67 + 8649463 = 8649530
79 + 8649451 = 8649530
139 + 8649391 = 8649530
163 + 8649367 = 8649530
181 + 8649349 = 8649530
199 + 8649331 = 8649530

Showing the first eight; more decompositions exist.
