Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168500, here are decompositions:

19 + 168481 = 168500
37 + 168463 = 168500
43 + 168457 = 168500
67 + 168433 = 168500
109 + 168391 = 168500
223 + 168277 = 168500
307 + 168193 = 168500
349 + 168151 = 168500

Showing the first eight; more decompositions exist.
