Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649284, here are decompositions:

31 + 8649253 = 8649284
43 + 8649241 = 8649284
73 + 8649211 = 8649284
97 + 8649187 = 8649284
181 + 8649103 = 8649284
223 + 8649061 = 8649284
283 + 8649001 = 8649284
331 + 8648953 = 8649284

Showing the first eight; more decompositions exist.
