Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591816, here are decompositions:

3 + 8591813 = 8591816
7 + 8591809 = 8591816
43 + 8591773 = 8591816
127 + 8591689 = 8591816
193 + 8591623 = 8591816
199 + 8591617 = 8591816
223 + 8591593 = 8591816
229 + 8591587 = 8591816

Showing the first eight; more decompositions exist.
