Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166636, here are decompositions:

5 + 166631 = 166636
17 + 166619 = 166636
23 + 166613 = 166636
149 + 166487 = 166636
179 + 166457 = 166636
227 + 166409 = 166636
233 + 166403 = 166636
317 + 166319 = 166636

Showing the first eight; more decompositions exist.
