Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31184, here are decompositions:

3 + 31181 = 31184
7 + 31177 = 31184
31 + 31153 = 31184
37 + 31147 = 31184
61 + 31123 = 31184
103 + 31081 = 31184
151 + 31033 = 31184
313 + 30871 = 31184

Showing the first eight; more decompositions exist.
