Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188806, here are decompositions:

5 + 188801 = 188806
53 + 188753 = 188806
113 + 188693 = 188806
173 + 188633 = 188806
197 + 188609 = 188806
227 + 188579 = 188806
347 + 188459 = 188806
389 + 188417 = 188806

Showing the first eight; more decompositions exist.
