Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991084, here are decompositions:

5 + 991079 = 991084
11 + 991073 = 991084
41 + 991043 = 991084
47 + 991037 = 991084
53 + 991031 = 991084
131 + 990953 = 991084
167 + 990917 = 991084
191 + 990893 = 991084

Showing the first eight; more decompositions exist.
