Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649270, here are decompositions:

17 + 8649253 = 8649270
29 + 8649241 = 8649270
31 + 8649239 = 8649270
43 + 8649227 = 8649270
59 + 8649211 = 8649270
73 + 8649197 = 8649270
79 + 8649191 = 8649270
83 + 8649187 = 8649270

Showing the first eight; more decompositions exist.
