Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166824, here are decompositions:

17 + 166807 = 166824
41 + 166783 = 166824
43 + 166781 = 166824
83 + 166741 = 166824
101 + 166723 = 166824
131 + 166693 = 166824
157 + 166667 = 166824
167 + 166657 = 166824

Showing the first eight; more decompositions exist.
