Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991068, here are decompositions:

5 + 991063 = 991068
11 + 991057 = 991068
31 + 991037 = 991068
37 + 991031 = 991068
41 + 991027 = 991068
59 + 991009 = 991068
79 + 990989 = 991068
101 + 990967 = 991068

Showing the first eight; more decompositions exist.
