Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81882, here are decompositions:

13 + 81869 = 81882
29 + 81853 = 81882
43 + 81839 = 81882
83 + 81799 = 81882
109 + 81773 = 81882
113 + 81769 = 81882
179 + 81703 = 81882
181 + 81701 = 81882

Showing the first eight; more decompositions exist.
