Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591644, here are decompositions:

11 + 8591633 = 8591644
41 + 8591603 = 8591644
71 + 8591573 = 8591644
101 + 8591543 = 8591644
137 + 8591507 = 8591644
263 + 8591381 = 8591644
317 + 8591327 = 8591644
353 + 8591291 = 8591644

Showing the first eight; more decompositions exist.
