Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188938, here are decompositions:

5 + 188933 = 188938
11 + 188927 = 188938
47 + 188891 = 188938
107 + 188831 = 188938
137 + 188801 = 188938
227 + 188711 = 188938
251 + 188687 = 188938
257 + 188681 = 188938

Showing the first eight; more decompositions exist.
