Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591958, here are decompositions:

17 + 8591941 = 8591958
31 + 8591927 = 8591958
59 + 8591899 = 8591958
71 + 8591887 = 8591958
127 + 8591831 = 8591958
131 + 8591827 = 8591958
149 + 8591809 = 8591958
211 + 8591747 = 8591958

Showing the first eight; more decompositions exist.
