Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71184, here are decompositions:

13 + 71171 = 71184
17 + 71167 = 71184
23 + 71161 = 71184
31 + 71153 = 71184
37 + 71147 = 71184
41 + 71143 = 71184
103 + 71081 = 71184
173 + 71011 = 71184

Showing the first eight; more decompositions exist.
