Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185458, here are decompositions:

17 + 185441 = 185458
29 + 185429 = 185458
89 + 185369 = 185458
131 + 185327 = 185458
149 + 185309 = 185458
167 + 185291 = 185458
191 + 185267 = 185458
269 + 185189 = 185458

Showing the first eight; more decompositions exist.
