Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649622, here are decompositions:

11 + 8649611 = 8649622
41 + 8649581 = 8649622
89 + 8649533 = 8649622
101 + 8649521 = 8649622
131 + 8649491 = 8649622
239 + 8649383 = 8649622
251 + 8649371 = 8649622
269 + 8649353 = 8649622

Showing the first eight; more decompositions exist.
