Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991324, here are decompositions:

11 + 991313 = 991324
101 + 991223 = 991324
107 + 991217 = 991324
137 + 991187 = 991324
197 + 991127 = 991324
233 + 991091 = 991324
251 + 991073 = 991324
281 + 991043 = 991324

Showing the first eight; more decompositions exist.
