Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186366, here are decompositions:

23 + 186343 = 186366
67 + 186299 = 186366
83 + 186283 = 186366
107 + 186259 = 186366
113 + 186253 = 186366
127 + 186239 = 186366
137 + 186229 = 186366
139 + 186227 = 186366

Showing the first eight; more decompositions exist.
