Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186248, here are decompositions:

19 + 186229 = 186248
37 + 186211 = 186248
61 + 186187 = 186248
151 + 186097 = 186248
199 + 186049 = 186248
211 + 186037 = 186248
229 + 186019 = 186248
241 + 186007 = 186248

Showing the first eight; more decompositions exist.
