Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166904, here are decompositions:

37 + 166867 = 166904
43 + 166861 = 166904
61 + 166843 = 166904
97 + 166807 = 166904
163 + 166741 = 166904
181 + 166723 = 166904
211 + 166693 = 166904
277 + 166627 = 166904

Showing the first eight; more decompositions exist.
