Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649772, here are decompositions:

11 + 8649761 = 8649772
83 + 8649689 = 8649772
101 + 8649671 = 8649772
149 + 8649623 = 8649772
191 + 8649581 = 8649772
239 + 8649533 = 8649772
251 + 8649521 = 8649772
281 + 8649491 = 8649772

Showing the first eight; more decompositions exist.
