Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991054, here are decompositions:

11 + 991043 = 991054
17 + 991037 = 991054
23 + 991031 = 991054
101 + 990953 = 991054
131 + 990923 = 991054
137 + 990917 = 991054
167 + 990887 = 991054
173 + 990881 = 991054

Showing the first eight; more decompositions exist.
