Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005198, here are decompositions:

11 + 1005187 = 1005198
37 + 1005161 = 1005198
67 + 1005131 = 1005198
97 + 1005101 = 1005198
127 + 1005071 = 1005198
149 + 1005049 = 1005198
157 + 1005041 = 1005198
179 + 1005019 = 1005198

Showing the first eight; more decompositions exist.
