Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644080, here are decompositions:

19 + 8644061 = 8644080
23 + 8644057 = 8644080
31 + 8644049 = 8644080
61 + 8644019 = 8644080
83 + 8643997 = 8644080
89 + 8643991 = 8644080
127 + 8643953 = 8644080
139 + 8643941 = 8644080

Showing the first eight; more decompositions exist.
