Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187300, here are decompositions:

23 + 187277 = 187300
83 + 187217 = 187300
89 + 187211 = 187300
107 + 187193 = 187300
137 + 187163 = 187300
167 + 187133 = 187300
173 + 187127 = 187300
227 + 187073 = 187300

Showing the first eight; more decompositions exist.
