Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166854, here are decompositions:

5 + 166849 = 166854
7 + 166847 = 166854
11 + 166843 = 166854
13 + 166841 = 166854
31 + 166823 = 166854
47 + 166807 = 166854
71 + 166783 = 166854
73 + 166781 = 166854

Showing the first eight; more decompositions exist.
