Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166884, here are decompositions:

13 + 166871 = 166884
17 + 166867 = 166884
23 + 166861 = 166884
31 + 166853 = 166884
37 + 166847 = 166884
41 + 166843 = 166884
43 + 166841 = 166884
61 + 166823 = 166884

Showing the first eight; more decompositions exist.
