Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164986, here are decompositions:

23 + 164963 = 164986
149 + 164837 = 164986
197 + 164789 = 164986
257 + 164729 = 164986
359 + 164627 = 164986
509 + 164477 = 164986
557 + 164429 = 164986
599 + 164387 = 164986

Showing the first eight; more decompositions exist.
