Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164542, here are decompositions:

11 + 164531 = 164542
29 + 164513 = 164542
71 + 164471 = 164542
113 + 164429 = 164542
179 + 164363 = 164542
233 + 164309 = 164542
251 + 164291 = 164542
263 + 164279 = 164542

Showing the first eight; more decompositions exist.
