Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649330, here are decompositions:

7 + 8649323 = 8649330
13 + 8649317 = 8649330
31 + 8649299 = 8649330
37 + 8649293 = 8649330
47 + 8649283 = 8649330
89 + 8649241 = 8649330
103 + 8649227 = 8649330
139 + 8649191 = 8649330

Showing the first eight; more decompositions exist.
