Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161952, here are decompositions:

5 + 161947 = 161952
29 + 161923 = 161952
31 + 161921 = 161952
41 + 161911 = 161952
71 + 161881 = 161952
73 + 161879 = 161952
79 + 161873 = 161952
83 + 161869 = 161952

Showing the first eight; more decompositions exist.
