Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81952, here are decompositions:

23 + 81929 = 81952
53 + 81899 = 81952
83 + 81869 = 81952
113 + 81839 = 81952
179 + 81773 = 81952
191 + 81761 = 81952
251 + 81701 = 81952
263 + 81689 = 81952

Showing the first eight; more decompositions exist.
