Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164668, here are decompositions:

5 + 164663 = 164668
41 + 164627 = 164668
47 + 164621 = 164668
137 + 164531 = 164668
191 + 164477 = 164668
197 + 164471 = 164668
239 + 164429 = 164668
281 + 164387 = 164668

Showing the first eight; more decompositions exist.
