Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989128, here are decompositions:

5 + 989123 = 989128
29 + 989099 = 989128
47 + 989081 = 989128
149 + 988979 = 989128
191 + 988937 = 989128
227 + 988901 = 989128
251 + 988877 = 989128
269 + 988859 = 989128

Showing the first eight; more decompositions exist.
