Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991044, here are decompositions:

7 + 991037 = 991044
13 + 991031 = 991044
17 + 991027 = 991044
71 + 990973 = 991044
83 + 990961 = 991044
127 + 990917 = 991044
151 + 990893 = 991044
157 + 990887 = 991044

Showing the first eight; more decompositions exist.
