Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991270, here are decompositions:

41 + 991229 = 991270
47 + 991223 = 991270
53 + 991217 = 991270
83 + 991187 = 991270
89 + 991181 = 991270
179 + 991091 = 991270
191 + 991079 = 991270
197 + 991073 = 991270

Showing the first eight; more decompositions exist.
