Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591748, here are decompositions:

31 + 8591717 = 8591748
37 + 8591711 = 8591748
59 + 8591689 = 8591748
131 + 8591617 = 8591748
149 + 8591599 = 8591748
199 + 8591549 = 8591748
229 + 8591519 = 8591748
241 + 8591507 = 8591748

Showing the first eight; more decompositions exist.
