Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165936, here are decompositions:

5 + 165931 = 165936
53 + 165883 = 165936
59 + 165877 = 165936
79 + 165857 = 165936
103 + 165833 = 165936
107 + 165829 = 165936
137 + 165799 = 165936
157 + 165779 = 165936

Showing the first eight; more decompositions exist.
