Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164522, here are decompositions:

19 + 164503 = 164522
73 + 164449 = 164522
79 + 164443 = 164522
103 + 164419 = 164522
109 + 164413 = 164522
151 + 164371 = 164522
181 + 164341 = 164522
223 + 164299 = 164522

Showing the first eight; more decompositions exist.
