Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188972, here are decompositions:

19 + 188953 = 188972
31 + 188941 = 188972
61 + 188911 = 188972
103 + 188869 = 188972
109 + 188863 = 188972
139 + 188833 = 188972
181 + 188791 = 188972
193 + 188779 = 188972

Showing the first eight; more decompositions exist.
