Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164218, here are decompositions:

17 + 164201 = 164218
71 + 164147 = 164218
101 + 164117 = 164218
167 + 164051 = 164218
179 + 164039 = 164218
227 + 163991 = 164218
239 + 163979 = 164218
317 + 163901 = 164218

Showing the first eight; more decompositions exist.
