Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23198, here are decompositions:

31 + 23167 = 23198
67 + 23131 = 23198
127 + 23071 = 23198
139 + 23059 = 23198
157 + 23041 = 23198
181 + 23017 = 23198
277 + 22921 = 23198
337 + 22861 = 23198

Showing the first eight; more decompositions exist.
