Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591656, here are decompositions:

23 + 8591633 = 8591656
53 + 8591603 = 8591656
83 + 8591573 = 8591656
107 + 8591549 = 8591656
113 + 8591543 = 8591656
137 + 8591519 = 8591656
149 + 8591507 = 8591656
173 + 8591483 = 8591656

Showing the first eight; more decompositions exist.
