Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649276, here are decompositions:

23 + 8649253 = 8649276
37 + 8649239 = 8649276
79 + 8649197 = 8649276
89 + 8649187 = 8649276
173 + 8649103 = 8649276
197 + 8649079 = 8649276
227 + 8649049 = 8649276
347 + 8648929 = 8649276

Showing the first eight; more decompositions exist.
