Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162568, here are decompositions:

5 + 162563 = 162568
11 + 162557 = 162568
41 + 162527 = 162568
149 + 162419 = 162568
179 + 162389 = 162568
281 + 162287 = 162568
311 + 162257 = 162568
317 + 162251 = 162568

Showing the first eight; more decompositions exist.
