Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005208, here are decompositions:

5 + 1005203 = 1005208
47 + 1005161 = 1005208
101 + 1005107 = 1005208
107 + 1005101 = 1005208
137 + 1005071 = 1005208
167 + 1005041 = 1005208
179 + 1005029 = 1005208
227 + 1004981 = 1005208

Showing the first eight; more decompositions exist.
