Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591740, here are decompositions:

23 + 8591717 = 8591740
29 + 8591711 = 8591740
107 + 8591633 = 8591740
137 + 8591603 = 8591740
167 + 8591573 = 8591740
191 + 8591549 = 8591740
197 + 8591543 = 8591740
233 + 8591507 = 8591740

Showing the first eight; more decompositions exist.
