Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164886, here are decompositions:

5 + 164881 = 164886
47 + 164839 = 164886
97 + 164789 = 164886
157 + 164729 = 164886
179 + 164707 = 164886
223 + 164663 = 164886
233 + 164653 = 164886
263 + 164623 = 164886

Showing the first eight; more decompositions exist.
