Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641552, here are decompositions:

5 + 8641547 = 8641552
11 + 8641541 = 8641552
83 + 8641469 = 8641552
131 + 8641421 = 8641552
191 + 8641361 = 8641552
233 + 8641319 = 8641552
251 + 8641301 = 8641552
263 + 8641289 = 8641552

Showing the first eight; more decompositions exist.
