Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165894, here are decompositions:

7 + 165887 = 165894
11 + 165883 = 165894
17 + 165877 = 165894
37 + 165857 = 165894
61 + 165833 = 165894
83 + 165811 = 165894
173 + 165721 = 165894
181 + 165713 = 165894

Showing the first eight; more decompositions exist.
