Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591994, here are decompositions:

31 + 8591963 = 8591994
53 + 8591941 = 8591994
67 + 8591927 = 8591994
107 + 8591887 = 8591994
163 + 8591831 = 8591994
167 + 8591827 = 8591994
181 + 8591813 = 8591994
223 + 8591771 = 8591994

Showing the first eight; more decompositions exist.
