Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649208, here are decompositions:

11 + 8649197 = 8649208
17 + 8649191 = 8649208
137 + 8649071 = 8649208
179 + 8649029 = 8649208
461 + 8648747 = 8649208
467 + 8648741 = 8649208
479 + 8648729 = 8649208
521 + 8648687 = 8649208

Showing the first eight; more decompositions exist.
