Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991074, here are decompositions:

5 + 991069 = 991074
11 + 991063 = 991074
17 + 991057 = 991074
31 + 991043 = 991074
37 + 991037 = 991074
43 + 991031 = 991074
47 + 991027 = 991074
101 + 990973 = 991074

Showing the first eight; more decompositions exist.
