Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187066, here are decompositions:

17 + 187049 = 187066
23 + 187043 = 187066
107 + 186959 = 187066
149 + 186917 = 187066
197 + 186869 = 187066
293 + 186773 = 187066
359 + 186707 = 187066
419 + 186647 = 187066

Showing the first eight; more decompositions exist.
