Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185166, here are decompositions:

5 + 185161 = 185166
13 + 185153 = 185166
17 + 185149 = 185166
29 + 185137 = 185166
43 + 185123 = 185166
67 + 185099 = 185166
89 + 185077 = 185166
97 + 185069 = 185166

Showing the first eight; more decompositions exist.
