Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188982, here are decompositions:

29 + 188953 = 188982
41 + 188941 = 188982
43 + 188939 = 188982
71 + 188911 = 188982
113 + 188869 = 188982
139 + 188843 = 188982
149 + 188833 = 188982
151 + 188831 = 188982

Showing the first eight; more decompositions exist.
