Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185266, here are decompositions:

23 + 185243 = 185266
83 + 185183 = 185266
89 + 185177 = 185266
113 + 185153 = 185266
167 + 185099 = 185266
197 + 185069 = 185266
239 + 185027 = 185266
269 + 184997 = 185266

Showing the first eight; more decompositions exist.
