Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641152, here are decompositions:

5 + 8641147 = 8641152
19 + 8641133 = 8641152
59 + 8641093 = 8641152
73 + 8641079 = 8641152
89 + 8641063 = 8641152
241 + 8640911 = 8641152
263 + 8640889 = 8641152
269 + 8640883 = 8641152

Showing the first eight; more decompositions exist.
