Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991096, here are decompositions:

5 + 991091 = 991096
17 + 991079 = 991096
23 + 991073 = 991096
53 + 991043 = 991096
59 + 991037 = 991096
107 + 990989 = 991096
173 + 990923 = 991096
179 + 990917 = 991096

Showing the first eight; more decompositions exist.
