Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164650, here are decompositions:

23 + 164627 = 164650
29 + 164621 = 164650
137 + 164513 = 164650
173 + 164477 = 164650
179 + 164471 = 164650
263 + 164387 = 164650
293 + 164357 = 164650
359 + 164291 = 164650

Showing the first eight; more decompositions exist.
