Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005142, here are decompositions:

11 + 1005131 = 1005142
41 + 1005101 = 1005142
71 + 1005071 = 1005142
101 + 1005041 = 1005142
113 + 1005029 = 1005142
179 + 1004963 = 1005142
239 + 1004903 = 1005142
269 + 1004873 = 1005142

Showing the first eight; more decompositions exist.
