Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164464, here are decompositions:

17 + 164447 = 164464
101 + 164363 = 164464
107 + 164357 = 164464
173 + 164291 = 164464
197 + 164267 = 164464
233 + 164231 = 164464
263 + 164201 = 164464
281 + 164183 = 164464

Showing the first eight; more decompositions exist.
