Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991014, here are decompositions:

5 + 991009 = 991014
41 + 990973 = 991014
47 + 990967 = 991014
53 + 990961 = 991014
61 + 990953 = 991014
97 + 990917 = 991014
127 + 990887 = 991014
163 + 990851 = 991014

Showing the first eight; more decompositions exist.
