Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186266, here are decompositions:

7 + 186259 = 186266
13 + 186253 = 186266
19 + 186247 = 186266
37 + 186229 = 186266
79 + 186187 = 186266
103 + 186163 = 186266
109 + 186157 = 186266
163 + 186103 = 186266

Showing the first eight; more decompositions exist.
