Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185118, here are decompositions:

19 + 185099 = 185118
29 + 185089 = 185118
41 + 185077 = 185118
47 + 185071 = 185118
61 + 185057 = 185118
67 + 185051 = 185118
97 + 185021 = 185118
149 + 184969 = 185118

Showing the first eight; more decompositions exist.
