Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184900, here are decompositions:

41 + 184859 = 184900
71 + 184829 = 184900
167 + 184733 = 184900
173 + 184727 = 184900
179 + 184721 = 184900
197 + 184703 = 184900
251 + 184649 = 184900
269 + 184631 = 184900

Showing the first eight; more decompositions exist.
