Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164636, here are decompositions:

13 + 164623 = 164636
19 + 164617 = 164636
37 + 164599 = 164636
67 + 164569 = 164636
193 + 164443 = 164636
223 + 164413 = 164636
337 + 164299 = 164636
397 + 164239 = 164636

Showing the first eight; more decompositions exist.
