Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591916, here are decompositions:

7 + 8591909 = 8591916
17 + 8591899 = 8591916
29 + 8591887 = 8591916
89 + 8591827 = 8591916
103 + 8591813 = 8591916
107 + 8591809 = 8591916
199 + 8591717 = 8591916
227 + 8591689 = 8591916

Showing the first eight; more decompositions exist.
