Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161064, here are decompositions:

5 + 161059 = 161064
11 + 161053 = 161064
17 + 161047 = 161064
31 + 161033 = 161064
47 + 161017 = 161064
67 + 160997 = 161064
83 + 160981 = 161064
97 + 160967 = 161064

Showing the first eight; more decompositions exist.
