Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166756, here are decompositions:

17 + 166739 = 166756
53 + 166703 = 166756
89 + 166667 = 166756
113 + 166643 = 166756
137 + 166619 = 166756
269 + 166487 = 166756
347 + 166409 = 166756
353 + 166403 = 166756

Showing the first eight; more decompositions exist.
