Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991234, here are decompositions:

5 + 991229 = 991234
11 + 991223 = 991234
17 + 991217 = 991234
47 + 991187 = 991234
53 + 991181 = 991234
107 + 991127 = 991234
191 + 991043 = 991234
197 + 991037 = 991234

Showing the first eight; more decompositions exist.
