Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649654, here are decompositions:

17 + 8649637 = 8649654
31 + 8649623 = 8649654
43 + 8649611 = 8649654
73 + 8649581 = 8649654
137 + 8649517 = 8649654
163 + 8649491 = 8649654
191 + 8649463 = 8649654
263 + 8649391 = 8649654

Showing the first eight; more decompositions exist.
