Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187160, here are decompositions:

19 + 187141 = 187160
31 + 187129 = 187160
37 + 187123 = 187160
79 + 187081 = 187160
151 + 187009 = 187160
157 + 187003 = 187160
271 + 186889 = 187160
277 + 186883 = 187160

Showing the first eight; more decompositions exist.
