Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188930, here are decompositions:

3 + 188927 = 188930
19 + 188911 = 188930
61 + 188869 = 188930
67 + 188863 = 188930
73 + 188857 = 188930
97 + 188833 = 188930
103 + 188827 = 188930
139 + 188791 = 188930

Showing the first eight; more decompositions exist.
