Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168842, here are decompositions:

61 + 168781 = 168842
73 + 168769 = 168842
199 + 168643 = 168842
211 + 168631 = 168842
241 + 168601 = 168842
283 + 168559 = 168842
379 + 168463 = 168842
409 + 168433 = 168842

Showing the first eight; more decompositions exist.
