Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164672, here are decompositions:

19 + 164653 = 164672
73 + 164599 = 164672
103 + 164569 = 164672
223 + 164449 = 164672
229 + 164443 = 164672
241 + 164431 = 164672
331 + 164341 = 164672
373 + 164299 = 164672

Showing the first eight; more decompositions exist.
