Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161934, here are decompositions:

11 + 161923 = 161934
13 + 161921 = 161934
23 + 161911 = 161934
53 + 161881 = 161934
61 + 161873 = 161934
103 + 161831 = 161934
127 + 161807 = 161934
151 + 161783 = 161934

Showing the first eight; more decompositions exist.
