Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186726, here are decompositions:

17 + 186709 = 186726
19 + 186707 = 186726
37 + 186689 = 186726
47 + 186679 = 186726
73 + 186653 = 186726
79 + 186647 = 186726
97 + 186629 = 186726
107 + 186619 = 186726

Showing the first eight; more decompositions exist.
