Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649338, here are decompositions:

7 + 8649331 = 8649338
97 + 8649241 = 8649338
127 + 8649211 = 8649338
151 + 8649187 = 8649338
277 + 8649061 = 8649338
337 + 8649001 = 8649338
409 + 8648929 = 8649338
457 + 8648881 = 8649338

Showing the first eight; more decompositions exist.
