Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164458, here are decompositions:

11 + 164447 = 164458
29 + 164429 = 164458
71 + 164387 = 164458
101 + 164357 = 164458
137 + 164321 = 164458
149 + 164309 = 164458
167 + 164291 = 164458
179 + 164279 = 164458

Showing the first eight; more decompositions exist.
