Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164618, here are decompositions:

19 + 164599 = 164618
31 + 164587 = 164618
37 + 164581 = 164618
199 + 164419 = 164618
241 + 164377 = 164618
277 + 164341 = 164618
367 + 164251 = 164618
379 + 164239 = 164618

Showing the first eight; more decompositions exist.
