Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186178, here are decompositions:

17 + 186161 = 186178
29 + 186149 = 186178
59 + 186119 = 186178
71 + 186107 = 186178
107 + 186071 = 186178
137 + 186041 = 186178
191 + 185987 = 186178
227 + 185951 = 186178

Showing the first eight; more decompositions exist.
