Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71216, here are decompositions:

7 + 71209 = 71216
73 + 71143 = 71216
97 + 71119 = 71216
127 + 71089 = 71216
157 + 71059 = 71216
193 + 71023 = 71216
337 + 70879 = 71216
349 + 70867 = 71216

Showing the first eight; more decompositions exist.
