Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991344, here are decompositions:

17 + 991327 = 991344
31 + 991313 = 991344
71 + 991273 = 991344
83 + 991261 = 991344
127 + 991217 = 991344
157 + 991187 = 991344
163 + 991181 = 991344
173 + 991171 = 991344

Showing the first eight; more decompositions exist.
