Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991248, here are decompositions:

19 + 991229 = 991248
31 + 991217 = 991248
47 + 991201 = 991248
61 + 991187 = 991248
67 + 991181 = 991248
101 + 991147 = 991248
157 + 991091 = 991248
179 + 991069 = 991248

Showing the first eight; more decompositions exist.
