Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991024, here are decompositions:

71 + 990953 = 991024
101 + 990923 = 991024
107 + 990917 = 991024
131 + 990893 = 991024
137 + 990887 = 991024
173 + 990851 = 991024
227 + 990797 = 991024
257 + 990767 = 991024

Showing the first eight; more decompositions exist.
