Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648784, here are decompositions:

5 + 8648779 = 8648784
37 + 8648747 = 8648784
43 + 8648741 = 8648784
47 + 8648737 = 8648784
83 + 8648701 = 8648784
97 + 8648687 = 8648784
107 + 8648677 = 8648784
227 + 8648557 = 8648784

Showing the first eight; more decompositions exist.
