Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991296, here are decompositions:

23 + 991273 = 991296
67 + 991229 = 991296
73 + 991223 = 991296
79 + 991217 = 991296
109 + 991187 = 991296
149 + 991147 = 991296
167 + 991129 = 991296
223 + 991073 = 991296

Showing the first eight; more decompositions exist.
