Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649516, here are decompositions:

37 + 8649479 = 8649516
47 + 8649469 = 8649516
53 + 8649463 = 8649516
97 + 8649419 = 8649516
107 + 8649409 = 8649516
149 + 8649367 = 8649516
163 + 8649353 = 8649516
167 + 8649349 = 8649516

Showing the first eight; more decompositions exist.
