Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991050, here are decompositions:

7 + 991043 = 991050
13 + 991037 = 991050
19 + 991031 = 991050
23 + 991027 = 991050
41 + 991009 = 991050
61 + 990989 = 991050
83 + 990967 = 991050
89 + 990961 = 991050

Showing the first eight; more decompositions exist.
