Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164566, here are decompositions:

53 + 164513 = 164566
89 + 164477 = 164566
137 + 164429 = 164566
179 + 164387 = 164566
257 + 164309 = 164566
317 + 164249 = 164566
383 + 164183 = 164566
419 + 164147 = 164566

Showing the first eight; more decompositions exist.
