Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185258, here are decompositions:

37 + 185221 = 185258
97 + 185161 = 185258
109 + 185149 = 185258
127 + 185131 = 185258
181 + 185077 = 185258
379 + 184879 = 185258
421 + 184837 = 185258
547 + 184711 = 185258

Showing the first eight; more decompositions exist.
