Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184208, here are decompositions:

19 + 184189 = 184208
97 + 184111 = 184208
127 + 184081 = 184208
151 + 184057 = 184208
229 + 183979 = 184208
331 + 183877 = 184208
337 + 183871 = 184208
379 + 183829 = 184208

Showing the first eight; more decompositions exist.
