Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649612, here are decompositions:

31 + 8649581 = 8649612
79 + 8649533 = 8649612
149 + 8649463 = 8649612
193 + 8649419 = 8649612
229 + 8649383 = 8649612
241 + 8649371 = 8649612
263 + 8649349 = 8649612
269 + 8649343 = 8649612

Showing the first eight; more decompositions exist.
