Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991048, here are decompositions:

5 + 991043 = 991048
11 + 991037 = 991048
17 + 991031 = 991048
59 + 990989 = 991048
131 + 990917 = 991048
167 + 990881 = 991048
197 + 990851 = 991048
239 + 990809 = 991048

Showing the first eight; more decompositions exist.
