Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82142, here are decompositions:

3 + 82139 = 82142
13 + 82129 = 82142
103 + 82039 = 82142
139 + 82003 = 82142
199 + 81943 = 82142
211 + 81931 = 82142
223 + 81919 = 82142
241 + 81901 = 82142

Showing the first eight; more decompositions exist.
