Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648966, here are decompositions:

13 + 8648953 = 8648966
37 + 8648929 = 8648966
43 + 8648923 = 8648966
103 + 8648863 = 8648966
127 + 8648839 = 8648966
229 + 8648737 = 8648966
409 + 8648557 = 8648966
433 + 8648533 = 8648966

Showing the first eight; more decompositions exist.
