Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649628, here are decompositions:

5 + 8649623 = 8649628
17 + 8649611 = 8649628
47 + 8649581 = 8649628
107 + 8649521 = 8649628
137 + 8649491 = 8649628
149 + 8649479 = 8649628
257 + 8649371 = 8649628
311 + 8649317 = 8649628

Showing the first eight; more decompositions exist.
