Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188110, here are decompositions:

3 + 188107 = 188110
89 + 188021 = 188110
137 + 187973 = 188110
179 + 187931 = 188110
227 + 187883 = 188110
233 + 187877 = 188110
239 + 187871 = 188110
317 + 187793 = 188110

Showing the first eight; more decompositions exist.
