Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164160, here are decompositions:

11 + 164149 = 164160
13 + 164147 = 164160
43 + 164117 = 164160
47 + 164113 = 164160
67 + 164093 = 164160
71 + 164089 = 164160
89 + 164071 = 164160
103 + 164057 = 164160

Showing the first eight; more decompositions exist.
