Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166716, here are decompositions:

13 + 166703 = 166716
23 + 166693 = 166716
37 + 166679 = 166716
47 + 166669 = 166716
59 + 166657 = 166716
73 + 166643 = 166716
89 + 166627 = 166716
97 + 166619 = 166716

Showing the first eight; more decompositions exist.
