Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649712, here are decompositions:

23 + 8649689 = 8649712
41 + 8649671 = 8649712
83 + 8649629 = 8649712
89 + 8649623 = 8649712
101 + 8649611 = 8649712
131 + 8649581 = 8649712
179 + 8649533 = 8649712
191 + 8649521 = 8649712

Showing the first eight; more decompositions exist.
