Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991276, here are decompositions:

3 + 991273 = 991276
47 + 991229 = 991276
53 + 991223 = 991276
59 + 991217 = 991276
89 + 991187 = 991276
149 + 991127 = 991276
197 + 991079 = 991276
233 + 991043 = 991276

Showing the first eight; more decompositions exist.
