Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649258, here are decompositions:

5 + 8649253 = 8649258
17 + 8649241 = 8649258
19 + 8649239 = 8649258
31 + 8649227 = 8649258
47 + 8649211 = 8649258
61 + 8649197 = 8649258
67 + 8649191 = 8649258
71 + 8649187 = 8649258

Showing the first eight; more decompositions exist.
