Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991264, here are decompositions:

3 + 991261 = 991264
41 + 991223 = 991264
47 + 991217 = 991264
83 + 991181 = 991264
137 + 991127 = 991264
173 + 991091 = 991264
191 + 991073 = 991264
227 + 991037 = 991264

Showing the first eight; more decompositions exist.
