Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185284, here are decompositions:

17 + 185267 = 185284
41 + 185243 = 185284
101 + 185183 = 185284
107 + 185177 = 185284
131 + 185153 = 185284
227 + 185057 = 185284
233 + 185051 = 185284
257 + 185027 = 185284

Showing the first eight; more decompositions exist.
