Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164338, here are decompositions:

17 + 164321 = 164338
29 + 164309 = 164338
47 + 164291 = 164338
59 + 164279 = 164338
71 + 164267 = 164338
89 + 164249 = 164338
107 + 164231 = 164338
137 + 164201 = 164338

Showing the first eight; more decompositions exist.
