Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188884, here are decompositions:

23 + 188861 = 188884
41 + 188843 = 188884
53 + 188831 = 188884
83 + 188801 = 188884
131 + 188753 = 188884
173 + 188711 = 188884
191 + 188693 = 188884
197 + 188687 = 188884

Showing the first eight; more decompositions exist.
