Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649528, here are decompositions:

7 + 8649521 = 8649528
11 + 8649517 = 8649528
37 + 8649491 = 8649528
59 + 8649469 = 8649528
61 + 8649467 = 8649528
109 + 8649419 = 8649528
137 + 8649391 = 8649528
157 + 8649371 = 8649528

Showing the first eight; more decompositions exist.
