Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12782, here are decompositions:

19 + 12763 = 12782
43 + 12739 = 12782
61 + 12721 = 12782
79 + 12703 = 12782
163 + 12619 = 12782
181 + 12601 = 12782
193 + 12589 = 12782
199 + 12583 = 12782

Showing the first eight; more decompositions exist.
