Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185104, here are decompositions:

5 + 185099 = 185104
41 + 185063 = 185104
47 + 185057 = 185104
53 + 185051 = 185104
83 + 185021 = 185104
107 + 184997 = 185104
137 + 184967 = 185104
191 + 184913 = 185104

Showing the first eight; more decompositions exist.
