Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641450, here are decompositions:

17 + 8641433 = 8641450
29 + 8641421 = 8641450
89 + 8641361 = 8641450
101 + 8641349 = 8641450
131 + 8641319 = 8641450
149 + 8641301 = 8641450
239 + 8641211 = 8641450
263 + 8641187 = 8641450

Showing the first eight; more decompositions exist.
