Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649230, here are decompositions:

3 + 8649227 = 8649230
19 + 8649211 = 8649230
43 + 8649187 = 8649230
127 + 8649103 = 8649230
151 + 8649079 = 8649230
181 + 8649049 = 8649230
229 + 8649001 = 8649230
277 + 8648953 = 8649230

Showing the first eight; more decompositions exist.
