Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71312, here are decompositions:

19 + 71293 = 71312
79 + 71233 = 71312
103 + 71209 = 71312
151 + 71161 = 71312
193 + 71119 = 71312
223 + 71089 = 71312
313 + 70999 = 71312
331 + 70981 = 71312

Showing the first eight; more decompositions exist.
