Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591946, here are decompositions:

5 + 8591941 = 8591946
19 + 8591927 = 8591946
37 + 8591909 = 8591946
47 + 8591899 = 8591946
59 + 8591887 = 8591946
137 + 8591809 = 8591946
173 + 8591773 = 8591946
199 + 8591747 = 8591946

Showing the first eight; more decompositions exist.
