Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164212, here are decompositions:

3 + 164209 = 164212
11 + 164201 = 164212
29 + 164183 = 164212
173 + 164039 = 164212
233 + 163979 = 164212
239 + 163973 = 164212
311 + 163901 = 164212
353 + 163859 = 164212

Showing the first eight; more decompositions exist.
