Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591922, here are decompositions:

13 + 8591909 = 8591922
23 + 8591899 = 8591922
109 + 8591813 = 8591922
113 + 8591809 = 8591922
149 + 8591773 = 8591922
151 + 8591771 = 8591922
211 + 8591711 = 8591922
233 + 8591689 = 8591922

Showing the first eight; more decompositions exist.
