Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005168, here are decompositions:

7 + 1005161 = 1005168
37 + 1005131 = 1005168
61 + 1005107 = 1005168
67 + 1005101 = 1005168
89 + 1005079 = 1005168
97 + 1005071 = 1005168
127 + 1005041 = 1005168
139 + 1005029 = 1005168

Showing the first eight; more decompositions exist.
