Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991254, here are decompositions:

31 + 991223 = 991254
37 + 991217 = 991254
53 + 991201 = 991254
67 + 991187 = 991254
73 + 991181 = 991254
83 + 991171 = 991254
107 + 991147 = 991254
127 + 991127 = 991254

Showing the first eight; more decompositions exist.
