Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185344, here are decompositions:

17 + 185327 = 185344
41 + 185303 = 185344
53 + 185291 = 185344
101 + 185243 = 185344
167 + 185177 = 185344
191 + 185153 = 185344
281 + 185063 = 185344
293 + 185051 = 185344

Showing the first eight; more decompositions exist.
