Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185474, here are decompositions:

7 + 185467 = 185474
73 + 185401 = 185474
103 + 185371 = 185474
151 + 185323 = 185474
241 + 185233 = 185474
307 + 185167 = 185474
313 + 185161 = 185474
337 + 185137 = 185474

Showing the first eight; more decompositions exist.
