Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189008, here are decompositions:

67 + 188941 = 189008
97 + 188911 = 189008
139 + 188869 = 189008
151 + 188857 = 189008
181 + 188827 = 189008
229 + 188779 = 189008
241 + 188767 = 189008
307 + 188701 = 189008

Showing the first eight; more decompositions exist.
