Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649250, here are decompositions:

11 + 8649239 = 8649250
23 + 8649227 = 8649250
53 + 8649197 = 8649250
59 + 8649191 = 8649250
179 + 8649071 = 8649250
227 + 8649023 = 8649250
383 + 8648867 = 8649250
419 + 8648831 = 8649250

Showing the first eight; more decompositions exist.
