Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165960, here are decompositions:

13 + 165947 = 165960
19 + 165941 = 165960
29 + 165931 = 165960
59 + 165901 = 165960
73 + 165887 = 165960
83 + 165877 = 165960
103 + 165857 = 165960
127 + 165833 = 165960

Showing the first eight; more decompositions exist.
