Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166836, here are decompositions:

13 + 166823 = 166836
29 + 166807 = 166836
37 + 166799 = 166836
53 + 166783 = 166836
97 + 166739 = 166836
113 + 166723 = 166836
157 + 166679 = 166836
167 + 166669 = 166836

Showing the first eight; more decompositions exist.
