Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166684, here are decompositions:

5 + 166679 = 166684
17 + 166667 = 166684
41 + 166643 = 166684
53 + 166631 = 166684
71 + 166613 = 166684
83 + 166601 = 166684
113 + 166571 = 166684
197 + 166487 = 166684

Showing the first eight; more decompositions exist.
