Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71156, here are decompositions:

3 + 71153 = 71156
13 + 71143 = 71156
37 + 71119 = 71156
67 + 71089 = 71156
97 + 71059 = 71156
157 + 70999 = 71156
199 + 70957 = 71156
277 + 70879 = 71156

Showing the first eight; more decompositions exist.
