Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005144, here are decompositions:

11 + 1005133 = 1005144
13 + 1005131 = 1005144
37 + 1005107 = 1005144
43 + 1005101 = 1005144
71 + 1005073 = 1005144
73 + 1005071 = 1005144
103 + 1005041 = 1005144
131 + 1005013 = 1005144

Showing the first eight; more decompositions exist.
