Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184, here are decompositions:

3 + 181 = 184
5 + 179 = 184
11 + 173 = 184
17 + 167 = 184
47 + 137 = 184
53 + 131 = 184
71 + 113 = 184
83 + 101 = 184

Showing the first eight; more decompositions exist.
