Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991354, here are decompositions:

11 + 991343 = 991354
41 + 991313 = 991354
131 + 991223 = 991354
137 + 991217 = 991354
167 + 991187 = 991354
173 + 991181 = 991354
227 + 991127 = 991354
263 + 991091 = 991354

Showing the first eight; more decompositions exist.
