Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166942, here are decompositions:

11 + 166931 = 166942
23 + 166919 = 166942
71 + 166871 = 166942
89 + 166853 = 166942
101 + 166841 = 166942
239 + 166703 = 166942
263 + 166679 = 166942
311 + 166631 = 166942

Showing the first eight; more decompositions exist.
