Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12842, here are decompositions:

13 + 12829 = 12842
19 + 12823 = 12842
43 + 12799 = 12842
61 + 12781 = 12842
79 + 12763 = 12842
103 + 12739 = 12842
139 + 12703 = 12842
223 + 12619 = 12842

Showing the first eight; more decompositions exist.
