Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649240, here are decompositions:

13 + 8649227 = 8649240
29 + 8649211 = 8649240
43 + 8649197 = 8649240
53 + 8649187 = 8649240
137 + 8649103 = 8649240
179 + 8649061 = 8649240
191 + 8649049 = 8649240
211 + 8649029 = 8649240

Showing the first eight; more decompositions exist.
