Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164256, here are decompositions:

5 + 164251 = 164256
7 + 164249 = 164256
17 + 164239 = 164256
23 + 164233 = 164256
47 + 164209 = 164256
73 + 164183 = 164256
83 + 164173 = 164256
107 + 164149 = 164256

Showing the first eight; more decompositions exist.
