Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187008, here are decompositions:

5 + 187003 = 187008
61 + 186947 = 187008
131 + 186877 = 187008
137 + 186871 = 187008
139 + 186869 = 187008
149 + 186859 = 187008
167 + 186841 = 187008
251 + 186757 = 187008

Showing the first eight; more decompositions exist.
