Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188106, here are decompositions:

89 + 188017 = 188106
179 + 187927 = 188106
197 + 187909 = 188106
199 + 187907 = 188106
223 + 187883 = 188106
229 + 187877 = 188106
263 + 187843 = 188106
283 + 187823 = 188106

Showing the first eight; more decompositions exist.
