Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185186, here are decompositions:

3 + 185183 = 185186
19 + 185167 = 185186
37 + 185149 = 185186
97 + 185089 = 185186
109 + 185077 = 185186
193 + 184993 = 185186
229 + 184957 = 185186
283 + 184903 = 185186

Showing the first eight; more decompositions exist.
