Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166328, here are decompositions:

31 + 166297 = 166328
109 + 166219 = 166328
139 + 166189 = 166328
181 + 166147 = 166328
229 + 166099 = 166328
307 + 166021 = 166328
367 + 165961 = 166328
397 + 165931 = 166328

Showing the first eight; more decompositions exist.
