Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166108, here are decompositions:

167 + 165941 = 166108
251 + 165857 = 166108
359 + 165749 = 166108
389 + 165719 = 166108
401 + 165707 = 166108
491 + 165617 = 166108
521 + 165587 = 166108
557 + 165551 = 166108

Showing the first eight; more decompositions exist.
