Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649606, here are decompositions:

73 + 8649533 = 8649606
89 + 8649517 = 8649606
127 + 8649479 = 8649606
137 + 8649469 = 8649606
139 + 8649467 = 8649606
197 + 8649409 = 8649606
223 + 8649383 = 8649606
239 + 8649367 = 8649606

Showing the first eight; more decompositions exist.
