Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188166, here are decompositions:

7 + 188159 = 188166
19 + 188147 = 188166
23 + 188143 = 188166
29 + 188137 = 188166
59 + 188107 = 188166
137 + 188029 = 188166
149 + 188017 = 188166
179 + 187987 = 188166

Showing the first eight; more decompositions exist.
