Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188882, here are decompositions:

13 + 188869 = 188882
19 + 188863 = 188882
103 + 188779 = 188882
163 + 188719 = 188882
181 + 188701 = 188882
229 + 188653 = 188882
349 + 188533 = 188882
409 + 188473 = 188882

Showing the first eight; more decompositions exist.
