Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185300, here are decompositions:

67 + 185233 = 185300
79 + 185221 = 185300
139 + 185161 = 185300
151 + 185149 = 185300
163 + 185137 = 185300
211 + 185089 = 185300
223 + 185077 = 185300
229 + 185071 = 185300

Showing the first eight; more decompositions exist.
