Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165798, here are decompositions:

19 + 165779 = 165798
79 + 165719 = 165798
89 + 165709 = 165798
97 + 165701 = 165798
131 + 165667 = 165798
181 + 165617 = 165798
197 + 165601 = 165798
211 + 165587 = 165798

Showing the first eight; more decompositions exist.
