Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185162, here are decompositions:

13 + 185149 = 185162
31 + 185131 = 185162
73 + 185089 = 185162
163 + 184999 = 185162
193 + 184969 = 185162
283 + 184879 = 185162
331 + 184831 = 185162
409 + 184753 = 185162

Showing the first eight; more decompositions exist.
