Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162856, here are decompositions:

3 + 162853 = 162856
17 + 162839 = 162856
107 + 162749 = 162856
173 + 162683 = 162856
179 + 162677 = 162856
227 + 162629 = 162856
233 + 162623 = 162856
263 + 162593 = 162856

Showing the first eight; more decompositions exist.
