Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042884, here are decompositions:

23 + 1042861 = 1042884
47 + 1042837 = 1042884
103 + 1042781 = 1042884
151 + 1042733 = 1042884
181 + 1042703 = 1042884
191 + 1042693 = 1042884
197 + 1042687 = 1042884
251 + 1042633 = 1042884

Showing the first eight; more decompositions exist.
