Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649474, here are decompositions:

5 + 8649469 = 8649474
7 + 8649467 = 8649474
11 + 8649463 = 8649474
23 + 8649451 = 8649474
83 + 8649391 = 8649474
103 + 8649371 = 8649474
107 + 8649367 = 8649474
131 + 8649343 = 8649474

Showing the first eight; more decompositions exist.
