Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71282, here are decompositions:

19 + 71263 = 71282
73 + 71209 = 71282
139 + 71143 = 71282
163 + 71119 = 71282
193 + 71089 = 71282
223 + 71059 = 71282
271 + 71011 = 71282
283 + 70999 = 71282

Showing the first eight; more decompositions exist.
