Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185022, here are decompositions:

23 + 184999 = 185022
29 + 184993 = 185022
53 + 184969 = 185022
73 + 184949 = 185022
109 + 184913 = 185022
163 + 184859 = 185022
179 + 184843 = 185022
191 + 184831 = 185022

Showing the first eight; more decompositions exist.
