Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991036, here are decompositions:

5 + 991031 = 991036
47 + 990989 = 991036
83 + 990953 = 991036
113 + 990923 = 991036
149 + 990887 = 991036
227 + 990809 = 991036
239 + 990797 = 991036
269 + 990767 = 991036

Showing the first eight; more decompositions exist.
