Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164386, here are decompositions:

23 + 164363 = 164386
29 + 164357 = 164386
107 + 164279 = 164386
137 + 164249 = 164386
239 + 164147 = 164386
269 + 164117 = 164386
293 + 164093 = 164386
347 + 164039 = 164386

Showing the first eight; more decompositions exist.
