Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991062, here are decompositions:

5 + 991057 = 991062
19 + 991043 = 991062
31 + 991031 = 991062
53 + 991009 = 991062
73 + 990989 = 991062
89 + 990973 = 991062
101 + 990961 = 991062
109 + 990953 = 991062

Showing the first eight; more decompositions exist.
