Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591940, here are decompositions:

13 + 8591927 = 8591940
31 + 8591909 = 8591940
41 + 8591899 = 8591940
53 + 8591887 = 8591940
109 + 8591831 = 8591940
113 + 8591827 = 8591940
127 + 8591813 = 8591940
131 + 8591809 = 8591940

Showing the first eight; more decompositions exist.
