Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185404, here are decompositions:

3 + 185401 = 185404
41 + 185363 = 185404
101 + 185303 = 185404
113 + 185291 = 185404
137 + 185267 = 185404
227 + 185177 = 185404
251 + 185153 = 185404
281 + 185123 = 185404

Showing the first eight; more decompositions exist.
