Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166906, here are decompositions:

53 + 166853 = 166906
59 + 166847 = 166906
83 + 166823 = 166906
107 + 166799 = 166906
167 + 166739 = 166906
227 + 166679 = 166906
239 + 166667 = 166906
263 + 166643 = 166906

Showing the first eight; more decompositions exist.
