Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188906, here are decompositions:

37 + 188869 = 188906
43 + 188863 = 188906
73 + 188833 = 188906
79 + 188827 = 188906
127 + 188779 = 188906
139 + 188767 = 188906
199 + 188707 = 188906
229 + 188677 = 188906

Showing the first eight; more decompositions exist.
