Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185464, here are decompositions:

23 + 185441 = 185464
101 + 185363 = 185464
137 + 185327 = 185464
173 + 185291 = 185464
197 + 185267 = 185464
281 + 185183 = 185464
311 + 185153 = 185464
401 + 185063 = 185464

Showing the first eight; more decompositions exist.
