Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991300, here are decompositions:

71 + 991229 = 991300
83 + 991217 = 991300
113 + 991187 = 991300
173 + 991127 = 991300
227 + 991073 = 991300
257 + 991043 = 991300
263 + 991037 = 991300
269 + 991031 = 991300

Showing the first eight; more decompositions exist.
