Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005284, here are decompositions:

43 + 1005241 = 1005284
61 + 1005223 = 1005284
67 + 1005217 = 1005284
97 + 1005187 = 1005284
151 + 1005133 = 1005284
211 + 1005073 = 1005284
271 + 1005013 = 1005284
277 + 1005007 = 1005284

Showing the first eight; more decompositions exist.
