Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189198, here are decompositions:

11 + 189187 = 189198
29 + 189169 = 189198
47 + 189151 = 189198
59 + 189139 = 189198
71 + 189127 = 189198
131 + 189067 = 189198
137 + 189061 = 189198
157 + 189041 = 189198

Showing the first eight; more decompositions exist.
