Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185208, here are decompositions:

19 + 185189 = 185208
31 + 185177 = 185208
41 + 185167 = 185208
47 + 185161 = 185208
59 + 185149 = 185208
71 + 185137 = 185208
109 + 185099 = 185208
131 + 185077 = 185208

Showing the first eight; more decompositions exist.
