Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001128, here are decompositions:

5 + 1001123 = 1001128
41 + 1001087 = 1001128
47 + 1001081 = 1001128
59 + 1001069 = 1001128
101 + 1001027 = 1001128
197 + 1000931 = 1001128
239 + 1000889 = 1001128
269 + 1000859 = 1001128

Showing the first eight; more decompositions exist.
