Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164770, here are decompositions:

3 + 164767 = 164770
41 + 164729 = 164770
107 + 164663 = 164770
149 + 164621 = 164770
239 + 164531 = 164770
257 + 164513 = 164770
293 + 164477 = 164770
383 + 164387 = 164770

Showing the first eight; more decompositions exist.
