Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649508, here are decompositions:

17 + 8649491 = 8649508
29 + 8649479 = 8649508
41 + 8649467 = 8649508
89 + 8649419 = 8649508
137 + 8649371 = 8649508
191 + 8649317 = 8649508
269 + 8649239 = 8649508
281 + 8649227 = 8649508

Showing the first eight; more decompositions exist.
