Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71286, here are decompositions:

23 + 71263 = 71286
29 + 71257 = 71286
37 + 71249 = 71286
53 + 71233 = 71286
139 + 71147 = 71286
157 + 71129 = 71286
167 + 71119 = 71286
197 + 71089 = 71286

Showing the first eight; more decompositions exist.
