Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166726, here are decompositions:

3 + 166723 = 166726
23 + 166703 = 166726
47 + 166679 = 166726
59 + 166667 = 166726
83 + 166643 = 166726
107 + 166619 = 166726
113 + 166613 = 166726
239 + 166487 = 166726

Showing the first eight; more decompositions exist.
