Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185394, here are decompositions:

23 + 185371 = 185394
31 + 185363 = 185394
67 + 185327 = 185394
71 + 185323 = 185394
103 + 185291 = 185394
127 + 185267 = 185394
151 + 185243 = 185394
173 + 185221 = 185394

Showing the first eight; more decompositions exist.
