Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649260, here are decompositions:

7 + 8649253 = 8649260
19 + 8649241 = 8649260
73 + 8649187 = 8649260
157 + 8649103 = 8649260
181 + 8649079 = 8649260
199 + 8649061 = 8649260
211 + 8649049 = 8649260
307 + 8648953 = 8649260

Showing the first eight; more decompositions exist.
