Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81852, here are decompositions:

5 + 81847 = 81852
13 + 81839 = 81852
53 + 81799 = 81852
79 + 81773 = 81852
83 + 81769 = 81852
103 + 81749 = 81852
149 + 81703 = 81852
151 + 81701 = 81852

Showing the first eight; more decompositions exist.
