Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003128, here are decompositions:

17 + 1003111 = 1003128
19 + 1003109 = 1003128
31 + 1003097 = 1003128
37 + 1003091 = 1003128
41 + 1003087 = 1003128
79 + 1003049 = 1003128
89 + 1003039 = 1003128
109 + 1003019 = 1003128

Showing the first eight; more decompositions exist.
