Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185454, here are decompositions:

13 + 185441 = 185454
53 + 185401 = 185454
83 + 185371 = 185454
127 + 185327 = 185454
131 + 185323 = 185454
151 + 185303 = 185454
163 + 185291 = 185454
211 + 185243 = 185454

Showing the first eight; more decompositions exist.
