Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649636, here are decompositions:

7 + 8649629 = 8649636
13 + 8649623 = 8649636
103 + 8649533 = 8649636
157 + 8649479 = 8649636
167 + 8649469 = 8649636
173 + 8649463 = 8649636
227 + 8649409 = 8649636
269 + 8649367 = 8649636

Showing the first eight; more decompositions exist.
