Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168968, here are decompositions:

31 + 168937 = 168968
67 + 168901 = 168968
199 + 168769 = 168968
271 + 168697 = 168968
337 + 168631 = 168968
367 + 168601 = 168968
409 + 168559 = 168968
487 + 168481 = 168968

Showing the first eight; more decompositions exist.
