Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166648, here are decompositions:

5 + 166643 = 166648
17 + 166631 = 166648
29 + 166619 = 166648
47 + 166601 = 166648
107 + 166541 = 166648
191 + 166457 = 166648
239 + 166409 = 166648
347 + 166301 = 166648

Showing the first eight; more decompositions exist.
