Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164568, here are decompositions:

37 + 164531 = 164568
97 + 164471 = 164568
137 + 164431 = 164568
139 + 164429 = 164568
149 + 164419 = 164568
181 + 164387 = 164568
191 + 164377 = 164568
197 + 164371 = 164568

Showing the first eight; more decompositions exist.
