Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166678, here are decompositions:

11 + 166667 = 166678
47 + 166631 = 166678
59 + 166619 = 166678
107 + 166571 = 166678
137 + 166541 = 166678
191 + 166487 = 166678
269 + 166409 = 166678
359 + 166319 = 166678

Showing the first eight; more decompositions exist.
