Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991110, here are decompositions:

19 + 991091 = 991110
31 + 991079 = 991110
37 + 991073 = 991110
41 + 991069 = 991110
47 + 991063 = 991110
53 + 991057 = 991110
67 + 991043 = 991110
73 + 991037 = 991110

Showing the first eight; more decompositions exist.
