Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162556, here are decompositions:

3 + 162553 = 162556
29 + 162527 = 162556
83 + 162473 = 162556
137 + 162419 = 162556
167 + 162389 = 162556
197 + 162359 = 162556
263 + 162293 = 162556
269 + 162287 = 162556

Showing the first eight; more decompositions exist.
