Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038198, here are decompositions:

11 + 1038187 = 1038198
41 + 1038157 = 1038198
71 + 1038127 = 1038198
79 + 1038119 = 1038198
151 + 1038047 = 1038198
157 + 1038041 = 1038198
179 + 1038019 = 1038198
181 + 1038017 = 1038198

Showing the first eight; more decompositions exist.
