Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184158, here are decompositions:

5 + 184153 = 184158
41 + 184117 = 184158
47 + 184111 = 184158
71 + 184087 = 184158
101 + 184057 = 184158
127 + 184031 = 184158
151 + 184007 = 184158
179 + 183979 = 184158

Showing the first eight; more decompositions exist.
