Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68942, here are decompositions:

43 + 68899 = 68942
61 + 68881 = 68942
79 + 68863 = 68942
151 + 68791 = 68942
193 + 68749 = 68942
199 + 68743 = 68942
229 + 68713 = 68942
283 + 68659 = 68942

Showing the first eight; more decompositions exist.
