Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185292, here are decompositions:

59 + 185233 = 185292
71 + 185221 = 185292
103 + 185189 = 185292
109 + 185183 = 185292
131 + 185161 = 185292
139 + 185153 = 185292
193 + 185099 = 185292
223 + 185069 = 185292

Showing the first eight; more decompositions exist.
