Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71162, here are decompositions:

19 + 71143 = 71162
43 + 71119 = 71162
73 + 71089 = 71162
103 + 71059 = 71162
139 + 71023 = 71162
151 + 71011 = 71162
163 + 70999 = 71162
181 + 70981 = 71162

Showing the first eight; more decompositions exist.
