Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991348, here are decompositions:

5 + 991343 = 991348
131 + 991217 = 991348
167 + 991181 = 991348
257 + 991091 = 991348
269 + 991079 = 991348
311 + 991037 = 991348
317 + 991031 = 991348
359 + 990989 = 991348

Showing the first eight; more decompositions exist.
