Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166918, here are decompositions:

47 + 166871 = 166918
71 + 166847 = 166918
137 + 166781 = 166918
179 + 166739 = 166918
239 + 166679 = 166918
251 + 166667 = 166918
317 + 166601 = 166918
347 + 166571 = 166918

Showing the first eight; more decompositions exist.
