Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167866, here are decompositions:

3 + 167863 = 167866
5 + 167861 = 167866
89 + 167777 = 167866
107 + 167759 = 167866
137 + 167729 = 167866
233 + 167633 = 167866
239 + 167627 = 167866
269 + 167597 = 167866

Showing the first eight; more decompositions exist.
