Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164422, here are decompositions:

3 + 164419 = 164422
59 + 164363 = 164422
101 + 164321 = 164422
113 + 164309 = 164422
131 + 164291 = 164422
173 + 164249 = 164422
191 + 164231 = 164422
239 + 164183 = 164422

Showing the first eight; more decompositions exist.
