Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168200, here are decompositions:

3 + 168197 = 168200
7 + 168193 = 168200
73 + 168127 = 168200
157 + 168043 = 168200
163 + 168037 = 168200
229 + 167971 = 168200
283 + 167917 = 168200
313 + 167887 = 168200

Showing the first eight; more decompositions exist.
