Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164272, here are decompositions:

5 + 164267 = 164272
23 + 164249 = 164272
41 + 164231 = 164272
71 + 164201 = 164272
89 + 164183 = 164272
179 + 164093 = 164272
233 + 164039 = 164272
281 + 163991 = 164272

Showing the first eight; more decompositions exist.
