Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165954, here are decompositions:

7 + 165947 = 165954
13 + 165941 = 165954
23 + 165931 = 165954
53 + 165901 = 165954
67 + 165887 = 165954
71 + 165883 = 165954
97 + 165857 = 165954
137 + 165817 = 165954

Showing the first eight; more decompositions exist.
