Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185108, here are decompositions:

19 + 185089 = 185108
31 + 185077 = 185108
37 + 185071 = 185108
109 + 184999 = 185108
139 + 184969 = 185108
151 + 184957 = 185108
229 + 184879 = 185108
271 + 184837 = 185108

Showing the first eight; more decompositions exist.
