Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649522, here are decompositions:

5 + 8649517 = 8649522
31 + 8649491 = 8649522
43 + 8649479 = 8649522
53 + 8649469 = 8649522
59 + 8649463 = 8649522
71 + 8649451 = 8649522
103 + 8649419 = 8649522
113 + 8649409 = 8649522

Showing the first eight; more decompositions exist.
