Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185238, here are decompositions:

5 + 185233 = 185238
17 + 185221 = 185238
61 + 185177 = 185238
71 + 185167 = 185238
89 + 185149 = 185238
101 + 185137 = 185238
107 + 185131 = 185238
139 + 185099 = 185238

Showing the first eight; more decompositions exist.
