Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649266, here are decompositions:

13 + 8649253 = 8649266
79 + 8649187 = 8649266
163 + 8649103 = 8649266
313 + 8648953 = 8649266
337 + 8648929 = 8649266
433 + 8648833 = 8649266
487 + 8648779 = 8649266
709 + 8648557 = 8649266

Showing the first eight; more decompositions exist.
