Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188836, here are decompositions:

3 + 188833 = 188836
5 + 188831 = 188836
83 + 188753 = 188836
107 + 188729 = 188836
149 + 188687 = 188836
227 + 188609 = 188836
233 + 188603 = 188836
257 + 188579 = 188836

Showing the first eight; more decompositions exist.
