Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188872, here are decompositions:

3 + 188869 = 188872
11 + 188861 = 188872
29 + 188843 = 188872
41 + 188831 = 188872
71 + 188801 = 188872
179 + 188693 = 188872
191 + 188681 = 188872
239 + 188633 = 188872

Showing the first eight; more decompositions exist.
