Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646080, here are decompositions:

19 + 8646061 = 8646080
109 + 8645971 = 8646080
139 + 8645941 = 8646080
181 + 8645899 = 8646080
193 + 8645887 = 8646080
277 + 8645803 = 8646080
307 + 8645773 = 8646080
433 + 8645647 = 8646080

Showing the first eight; more decompositions exist.
