Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55198, here are decompositions:

71 + 55127 = 55198
89 + 55109 = 55198
137 + 55061 = 55198
149 + 55049 = 55198
197 + 55001 = 55198
239 + 54959 = 55198
257 + 54941 = 55198
281 + 54917 = 55198

Showing the first eight; more decompositions exist.
