Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649480, here are decompositions:

11 + 8649469 = 8649480
13 + 8649467 = 8649480
17 + 8649463 = 8649480
29 + 8649451 = 8649480
61 + 8649419 = 8649480
71 + 8649409 = 8649480
89 + 8649391 = 8649480
97 + 8649383 = 8649480

Showing the first eight; more decompositions exist.
