Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186338, here are decompositions:

37 + 186301 = 186338
67 + 186271 = 186338
79 + 186259 = 186338
109 + 186229 = 186338
127 + 186211 = 186338
151 + 186187 = 186338
181 + 186157 = 186338
241 + 186097 = 186338

Showing the first eight; more decompositions exist.
